Visionauta Terms of Use

Version:: v2026.4
Date:: September 16, 2026
Authoritative language:: Portuguese

Before anything else: the warnings that matter

Visionauta uses artificial intelligence. Artificial intelligence makes mistakes. It may describe things wrongly, it may invent things that are not in the image and it may fail to see what is right there.

For that reason, never use Visionauta as the only source for a decision when a mistake could hurt you. In particular:

Do not use it to cross the street or to orient yourself while moving around. Visionauta does not replace the white cane, the guide dog or your own perception.
Do not use it to check a medication dose. Confirm with the pharmacy, with the braille package insert or with a person.
Do not use it to identify allergens in food. A mistake here can be serious.
Do not use it in an emergency. Call 192 (SAMU, the ambulance service), 193 (Fire Department) or 190 (Police).

Section 6 details this. Read it.

1. Acceptance

To use Visionauta, you need to accept these Terms and the Privacy Policy. Without that acceptance, the application does not work.

We are saying this prominently because the law requires it (art. 9º, §3º, of the LGPD): you have the right to know, before deciding, that acceptance is a condition for the service.

What acceptance means:

You have read and agree with these Terms.
You have read and understood the Privacy Policy, which is an integral part of this contract.
You are at least 12 years old. If you are under 18, you need the agreement of a guardian.

What acceptance does NOT mean. Accepting these Terms does not authorize keeping content of yours. In anonymous mode — the default mode —, no content and no sensitive data is stored: no image, no audio, no transcript, no memory — only the technical operating statistics described in the Policy (section 2.1). Keeping content only happens if you create a Visionauta Account, and the authorization for that is requested at the account creation itself, in prominent text, for you to decide there.

The two modes. Visionauta's essential features work without an account, without sign-up and without login. If you want the enhanced experience — an assistant that remembers you from one session to the next —, you can create a Visionauta Account: with e-mail and password, with Google or with Apple. The account keeps, on encrypted servers, the images, the audio, the transcripts, the memories of your conversations, device sensor data and your location when you share it — this storage is necessary for the features the account offers, and it is what you authorize when you create it (Privacy Policy, sections 2 and 3). Plans and quotas may be different between the two modes (section 3). At account creation, you confirm that you are over 18 and reaffirm the acceptance of these Terms and of the Privacy Policy, together with the storage consent — in a single acceptance, checked by you on that very screen.

The Visionauta Account is only for people over 18. Use without an account remains available from the age of 12, with the agreement of a guardian for those under 18. An account created by someone under 18 is closed, with deletion of the data. Whoever creates an account declares that the e-mail provided is true and is theirs — it is through it that you recover access. The rules of the account are in section 7.4.

This document is available in an accessible format and can be read by the screen reader and by the application's own speech synthesis.

2. What Visionauta is

Visionauta is a visual assistant for people with visual impairment. It:

Reads texts and documents through the camera.
Describes objects, scenes and environments.
Talks in real time by voice about what the camera is seeing.
Answers questions about nearby places.
Speaks the answers with speech synthesis.
Describes unlabeled images and icons while you navigate with the screen reader (Visionauta Magic, on Android).
Works with Meta's Ray-Ban glasses, if you have them.
Remembers what was left from previous sessions — this feature, and the others that depend on storing the conversations, require the Visionauta Account. Without an account, the assistant simply starts each session from scratch, and no content is kept.

The essential features in the list above work with and without an account. Features that depend on storage belong to the account, and plans and quotas may be different between the two modes (section 3). Part of the app runs inside your device, without internet; part needs a connection and artificial intelligence models in the cloud. The Privacy Policy explains what goes where — and what is kept in each mode.

3. Plans, quotas and subscription

3.1 Where the quotas are

The quotas are not in this document. They are published in the application itself and on the product page, because they change over time — as the cost of the technology falls, as new features appear, as we learn how Visionauta is really used.

Keeping numbers in a legal document would force us to rewrite the Terms with every adjustment, and would make you have to accept them again because of a change that is often in your favor.

This does not mean that the quota can change out from under you. The next section says exactly what we guarantee.

3.2 What we guarantee to subscribers

The condition you contracted applies until the end of the period you paid for.

If you subscribe to Visionauta Plus in a month in which the allowance is X, that allowance is yours throughout that whole billing cycle — even if we change the quotas the next day. A reduction of the quota only reaches you at the following renewal, and only after being announced.

How it works in practice:

Monthly subscription: the condition in force at the time of contracting applies for the whole month paid for.
Change for less: applies from the next renewal, with notice before it happens. If you do not want to continue under the new condition, you can cancel before renewing and you are not charged.
Change for more: applies immediately, for everyone. It makes no sense to hold back an improvement.
Free plan: the free quotas may change at any time, because there is no contracting and no payment involved. Relevant changes are announced in the app.

The allowance is restored at each renewal. The unused balance expires at the end of the cycle and does not accumulate. The daily free quotas remain valid for subscribers and are consumed before the subscription allowance.

3.3 When the service becomes unavailable

Visionauta depends on third-party services in order to work — artificial intelligence providers, cloud providers and the app stores. When one of them goes down, changes its rules or shuts down a service, Visionauta may become unavailable or lose a feature, sometimes without prior notice to us.

What we do when this happens: if the service becomes unavailable for a relevant period within a cycle you paid for, you are entitled to an extension of the subscription for the equivalent time, or to a proportional refund — whichever you prefer. Just ask at privacidade@tensorial.com.br. There is no need to prove any loss.

What we do not do: we do not hide behind the supplier. The consumer relationship is yours with Refactoring, not with its supplier. If the problem is ours or of our chain, the responsibility is ours towards you, and it is up to us to settle it with the supplier afterwards.

Fortuitous event and force majeure — disaster, cut of a country's infrastructure, decision by an authority, war — follow article 393 of the Civil Code. Even in those cases, the right to the extension or to the proportional refund above remains valid, because it is not compensation for damages: it is you not paying for a service you did not receive.

3.4 Price and billing

The price and the period are those displayed in the store (Google Play or App Store) at the time of contracting, in your currency.

Billing is done exclusively by the store. We do not collect and we do not keep data of your card or of any means of payment.

3.5 Cancellation

You can cancel whenever you want, with no penalty, through the store itself:

Android: Play Store → Profile → Payments and subscriptions → Subscriptions.
iPhone: Settings → your name → Subscriptions.

After cancelling, the benefits continue until the end of the period already paid for, and there is no new charge.

Attention: uninstalling the application does not cancel the subscription. Cancellation is done in the store.

3.6 Right of withdrawal

Under article 49 of the Código de Defesa do Consumidor (Brazilian Consumer Protection Code), you may withdraw from the contract within 7 calendar days, counted from the purchase, and get your money back.

The refund is processed by the store where you bought it. If you have difficulty, write to contato@tensorial.com.br and we will help.

3.7 Price changes

We give notice in advance, through the application and through the store. A price increase for those who are already subscribers follows the store's consent rules: if you do not agree, you can cancel before the next renewal. Changes of quota follow the rule of section 3.2.

3.8 Use of the quotas

The quotas are personal, non-transferable and tied to the device. Resale is forbidden. The usage statement is available inside the application.

Today, the quotas and the subscription are per device — signing in with the same account on another device does not transfer quota or subscription. We may offer different plans, quotas or conditions to those who have an account — including benefits exclusive to registered users. Changes like that are announced in the application and, when they reach a subscription already in force, they follow the rule of section 3.2; for the free plan, the rule of the same section applies.

4. The content you send remains yours

The images you capture, what you say and what you write are yours. We do not claim ownership over any of it.

4.1 The licence you grant us

For the app to work, we need permission to process that content. You grant us a licence:

Limited to the purposes declared in the Privacy Policy. In anonymous mode: answering you at that instant, and nothing more. In account mode: also keeping the content and analyzing it to improve Visionauta and, if you have turned on the training switch, using it to train our models. Nothing beyond that.
Non-exclusive and without the right to sublicense, except to the processors listed in the Privacy Policy, which act on our behalf.
Revocable at any time, by you, at no cost.
Temporary: it ceases when the data is discarded, when you delete the account or when you request the deletion of your data.

This licence is not perpetual and is not irrevocable. When you delete your data or your account, it ends, and the corresponding content is eliminated under the terms of the Privacy Policy.

4.2 Use for training artificial intelligence models

Your data only goes into model training if — and only if — you have turned on the "Train the artificial intelligence" switch, available to those who have a Visionauta Account. It is an authorization separate from everything: separate from the acceptance of these Terms, and separate from the storage authorization you give when creating the account. It comes turned off, and turning it on or not does not change any feature of the app.

With the switch turned on, the data kept in your account — images, audio, transcripts, memories and numerical derivatives — may be used to train, fine-tune, evaluate and develop Visionauta's artificial intelligence models, including new models.

The limits, which apply even with the switch turned on:

We do not sell and we do not transfer. Your data is not sold, licensed or handed over to third parties for them to train their own models. The training is of Visionauta's models.
Data of people under 18 trains no model at all. The account is for people over 18 (section 1); an account discovered to belong to a minor is closed, with deletion of the data.
You can opt out. Turning off the switch stops your data from being used in any training from that point on. Deleting the account, moreover, erases the entire archive.
Without an account, there is no training. In anonymous mode nothing is kept — there is no corpus to train on.

About what happens when we start training. To this day, no model has been trained with data from Visionauta users. That is going to start happening, with the data of those who turn on the switch. And, from then on, the following applies: a model that has already been trained does not unlearn. That is why withdrawal applies going forward — it prevents your data from being used from that point on, but it does not undo training that has already happened before you turned it off. We are saying this now, before starting, because it is the kind of thing nobody wants to find out afterwards.

If this changes, the change is material and follows the rule of section 10: notice 30 days in advance and a new acceptance. It does not come into force in silence.

4.3 Our intellectual property

The application, its code, its interface, the "Visionauta" and "Tensorial" trademarks and the documentation belong to Refactoring Soluções em Tecnologia LTDA or to its licensors.

We grant you a personal, non-transferable, non-exclusive and revocable licence to use the application in accordance with these Terms. Nothing here transfers intellectual property to you.

Some components come from third parties, under their own licences, listed on the application's Licences screen. In particular, the local neural voice is based on the Supertonic model (Supertone Inc.), licensed under OpenRAIL-M; the restrictions of that licence are in section 7.3.

5. Other people who appear in the camera

This section exists because a visual assistant, by its very nature, captures more than the person using it.

When you point the camera, other people may appear in the image, and other voices may be picked up by the microphone. Those people are not Visionauta users and have not accepted anything.

How this works in each mode:

In anonymous mode, no content is kept. The person who walked in front of your camera does not remain in a photo, in a recording or in a transcript — the content is processed to generate the answer and discarded.
In account mode, what the camera saw is kept in your archive — and the scene may have included another person, who authorized nothing. We prefer to declare this rather than hide it: if you create an account, the images and the audio you capture, including third parties who are in the scene, go into the storage you authorized. That archive is yours, it is kept on an encrypted server, it is not sold or transferred, and it is erased when you delete the account.

For that reason, here is what we ask of you — and all the more so if you have an account:

Use Visionauta with the same good sense expected of any camera in a shared space.
Do not use the application to watch, monitor, identify or embarrass other people.
Respect places where image capture is prohibited or restricted.
If someone asks you not to point the camera, respect that.

You are responsible for the use you make of the camera. We have no way of controlling what comes into the frame.

If you are a person who appeared in someone's camera and want to exercise rights about that, write to privacidade@tensorial.com.br. We will answer. If the user was anonymous, the answer will probably be that there is no data of yours with us — nothing was kept. If the content is in the archive of an account, we will assess the request under the terms of the LGPD, weighing the rights of everyone involved.

6. Limits of the service — read carefully

6.1 Visionauta is an aid, not a substitute

Visionauta does not replace:

The white cane or the guide dog.
Human accompaniment in a risky situation.
Assessment by a health or vision professional.
Your own judgement.

6.2 Artificial intelligence makes mistakes

The descriptions are generated by artificial intelligence models. That means that:

They may be wrong.
They may contain hallucinations — the model confidently describing something that is not in the image.
They may omit what mattered most in the scene.
The quality depends on light, focus, angle, noise and connection.

We have no way of guaranteeing the accuracy of any specific answer.

6.3 Situations in which you should not rely on Visionauta alone

Emergencies. Do not use Visionauta to call for help. Call 192, 193 or 190.

Medications. Do not use Visionauta to check which medicine is which, what the dose is or the expiry date. A reading error here can be fatal. Confirm with the pharmacy or with a person.

Food and allergens. Do not use Visionauta as the only check of ingredients, allergens or expiry date.

Crossing the street and mobility. Do not use Visionauta to decide whether it is safe to cross, nor as a guide for moving around. There are three known ways of failing at exactly that moment: network delay, model error and the camera pointed at the wrong place. Keep using the white cane, the guide dog and the signalled crossings.

Financial and legal decisions. Do not sign, do not pay and do not authorize anything based only on what Visionauta read to you.

Identification of people. Visionauta is not an identification tool and must not be used as one.

In all of these cases: confirm by another means.

6.4 Location and places

Information about addresses, nearby places, opening hours and routes is informative. It may be out of date or wrong. It is not real-time navigation nor instruction for crossing the street.

6.5 Availability

The cloud features depend on the internet. The service may become unavailable for maintenance or because of a third-party failure. We do not guarantee uninterrupted operation.

7. Proper use

7.1 You agree not to

Use the application for an illegal purpose.
Attempt unauthorized access to our systems.
Reverse-engineer, decompile or disassemble the application.
Remove copyright notices or trademarks.
Overload the service or use automation to consume quota abusively.
Resell, sublicense or commercialize access.
Use the application to watch or embarrass other people (section 5).

7.2 Consequence

A violation may lead to suspension or termination of access. If you are a subscriber and the termination comes from us without you having violated anything, we refund the amount proportional to the unused period.

7.3 Restrictions of the neural voice (third-party licence)

The local neural voice uses the Supertonic model, under the OpenRAIL-M licence. As a condition of use, you agree not to use that voice to: violate the law; exploit or harm minors; generate disinformation with the intent of causing harm; defame, harass or stalk someone; impersonate another person, including by voice imitation or deepfake; discriminate against people or groups; exploit the vulnerability of vulnerable groups; give medical advice; or apply it in criminal justice, immigration or asylum.

These restrictions come from the model's licence and are passed on to you.

7.4 Account and credentials

If you create an account, these rules apply:

The password is yours and nobody else's. Do not share it — not even with us. We never ask for your password by e-mail, message or phone call; if someone asks, it is not us.
Whatever is done with your login counts as done by you. Keep the password with the same care with which you keep the one for your e-mail — all the more so now that the account keeps your archive of conversations.
If you suspect that someone got into your account, change the password right away — "Forgot my password", on the sign-in screen, sends a reset link to your e-mail — and let us know at privacidade@tensorial.com.br.
The e-mail must be true and yours. It is through it that you recover access and receive notices about the account. An account created with another person's e-mail may be suspended.

8. Privacy

The processing of your data is governed by the Privacy Policy, an integral part of these Terms.

The three points that matter most:

There are two ways to use Visionauta. In anonymous mode, no content of yours and no sensitive data is kept — only technical operating statistics. In account mode (for people over 18), Visionauta keeps your archive — images, audio, transcripts, memories, sensor data and location when shared — on encrypted servers, and analyzes it to improve the app; this storage is necessary for the account features. You authorize this at account creation, with the text on the screen.
Training the artificial intelligence models with your data is a separate and optional switch, which comes turned off and can be turned back off at any time.
You can erase: the data of a device, with a button in the app or a page on the website; and, if you have an account, the entire account with the whole archive, inside the app, confirming with your login.

9. Liability

9.1 What we take on

We are liable, under the terms of the Código de Defesa do Consumidor (Brazilian Consumer Protection Code), for defect or flaw in the service we provide, and for damage arising from it. We do not exclude that liability — a clause that excluded it would be null (art. 51, I, of the CDC).

9.2 What we do not take on

We are not liable for:

A decision you take contrary to the warnings of section 6 — for example, crossing the street or taking a medicine relying only on what the application said.
Third-party failure outside our control: your connection, your carrier, the app store, the device manufacturer.
Fortuitous event and force majeure.
Use of the application at odds with these Terms.

9.3 Limit

Except in cases of wilful misconduct, gross negligence or damage arising from a defect in the service, our total liability is limited to the greater of these amounts: the total paid by you in the 12 months preceding the event, or R$ 500.00.

That limit does not apply to any right that the law declares non-waivable.

9.4 No waiver of rights

Nothing in these Terms prevents you from:

Going to court, including in the courts of your own domicile.
Taking part in a class action.
Complaining to Procon or to a consumer protection body.
Petitioning the ANPD.

We do not require arbitration.

10. Changes to these Terms

As of this version, we give you notice 30 days in advance of any change to these Terms, by push notification and by notice inside the application.

A material change requires a new acceptance. Continued use, on its own, does not count as acceptance of a material change.

Each version is numbered, and the number of the version you accepted is recorded. The history is available at www.tensorial.com.br/visionauta/versoes.

We may alter, update or discontinue features. If we discontinue the service for subscribers, we refund the amount proportional to the unused period.

11. Termination

By you. There are four different things, which are easy to confuse — and confusing them costs money or leaves data behind. One by one:

Uninstalling the application removes the app from the device, and that is all. It does not cancel the subscription, it does not delete the account and it does not erase the data that is on our servers.
Cancelling the subscription is done in the store, never in the app (section 3.5): Play Store → Profile → Payments and subscriptions → Subscriptions, or iPhone Settings → your name → Subscriptions. The benefits continue until the end of the period paid for.
Deleting the account is done inside the app: Settings → Account → Delete account, confirming with your login. It erases the account and the entire archive — images, audio, transcripts, memories and derivatives — and the data of the linked devices. It does not cancel the subscription — that is a contract of yours with the store, and it continues until you cancel it there.
Deleting the data of a device — for those who do not have an account, or who want to erase only that device — is done with the button in the app (Settings → Privacy → Delete my data) or through the page www.tensorial.com.br/visionauta/excluir-dados.

None of these four depends on another: you can do any combination, in any order. What is retained after a deletion is in the Privacy Policy, section 10 — including the access logs that the Marco Civil da Internet obliges us to keep for 6 months.

By us: we may suspend or terminate access in the event of a violation of these Terms, of a need to protect the service or the other users, or of a legal determination. Whenever possible, we give notice beforehand and explain the reason.

What survives termination: the clauses on intellectual property, liability, applicable law and jurisdiction.

12. General provisions

These Terms and the Privacy Policy form the entire agreement between you and the company regarding the use of the application.

If any clause is held invalid, the others remain valid.

The fact that we do not exercise a right today does not mean that we waive it.

Language. In case of divergence between translations, the text in Portuguese prevails.

13. Applicable law and jurisdiction

These Terms are governed by the laws of Brazil.

The Central Courts of the Judicial District of São Paulo, SP, are hereby elected. If you are a consumer, this does not remove your right to sue in the courts of your own domicile, guaranteed by the Código de Defesa do Consumidor (Brazilian Consumer Protection Code).

Before resorting to the courts, the parties will seek an amicable solution — which is not a condition for access to justice.
