Audivision Privacy Policy

Last updated: 3 October 2026

This policy covers Audivision, the app for iPhone published by Audirivision Technologies Private Limited (“we”, “us”, “our”), together with its Apple Watch app and its widgets (together, “the app”). It describes what the app sends to us, what never leaves your phone, who else processes your data, how long we keep it, and how to delete your account.

Who is responsible for your data

Audirivision Technologies Private Limited, VO-505, 10th Floor, NESCO Tower 4, C Wing, Nesco IT Park, Western Express Highway, Goregaon (East), Mumbai 400063, India, decides what the app collects and why, and is responsible for looking after it (the “data fiduciary” under India’s Digital Personal Data Protection Act, 2023, and the “controller” in the language of the EU and UK GDPR). For anything in this policy, whether a question, a correction, a copy of what we hold, a deletion or a complaint, write to our Grievance Officer at contact@audivision.in. We answer within 30 days.

Your account (Sign in with Apple)

To use Audivision you sign in with your Apple Account. When you do, Apple shares with us:

• a stable identifier for your Apple Account that is specific to our apps;
• your name, if you choose to share it; and
• your email address, or, if you choose “Hide My Email”, a private relay address that Apple forwards to you.

Apple shares your name and email only the first time you sign in. Google Firebase Authentication creates your Audivision account from this and gives it an account identifier (the “account ID”). Your name, email and account ID are also kept in the app’s own storage on your phone so that the app can show who is signed in.

We use these to run your account, to recognise you when you sign in again (including on a new phone), to link your purchases and device registrations to you, and to answer you if you contact us. We do not send you marketing email.

Account profile and device information

Each time the app starts while you are signed in, it updates a profile record for your account. It contains:

When your app version, device, iOS version or language settings change, a copy of the profile as it now stands is also added to a history of that record, so that we know since when something has been true.

During setup, the app also asks what you mostly read and which language you read most often. Those two answers are stored against your account ID to understand what people use Audivision for.

Usage records

When a page or document is recognised and read, or exported, the app writes a short usage record against your account ID. It contains:

• what happened (for example “page processed” or “page exported”);
• the file type (for example “pdf” or “jpg”), its size in megabytes and the number of characters of text;
• the language you selected, the language detected, and whether automatic language detection was on;
• how the item was opened, as a category such as file picker, shared from another app, web address import or pasted text; and
• the date, the platform, and whether the account is anonymous (on iPhone it never is).

A usage record never contains the text, image or file itself, the file name, or the web address it came from. We use these records to see which formats, languages and features are used, and to find problems.

Purchases

Audivision offers an annual subscription and a one-time lifetime purchase. Apple processes the payment; we never receive your card or bank details. When a purchase completes, the app records your account ID, the product you bought, the App Store transaction number and the date. We use this to support your purchase, to answer questions about it, and for our accounts. Whether you currently have Premium is checked on your phone with the App Store, not from this record.

Account deletion requests

If you delete your account, the app sends a deletion request containing your account ID, a shortened one-way hash of it, the platform, the app version and the date. If you choose a reason for leaving, or type more detail (up to 500 characters), that is sent too. We use it to process the deletion and to learn why people leave. See Deleting your account.

Audivision hardware registration

If you own an Audivision hardware device and register it by scanning its QR code (menu › Device Registration), the app sends the device’s serial identifier, your account ID, your email address, the app version, your phone model, iOS version and language setting. We keep this as the record that the device is registered to you. If you never register a device, none of this is sent.

What the app asks our servers

Most of Audivision works without a connection. When it has one, the app makes these requests over an encrypted connection to our servers, which run on Google Cloud. Each carries your sign-in token and an app-integrity token (see below), from which our servers know your account ID.

• Content key. Some content bundled with the app is protected. The app asks for a key to unlock it, delivered sealed to a key pair generated on your phone.
• Book downloads. When you open a book from the built-in Books library, the app sends that book’s catalogue number to get a temporary download link, then downloads the book file from Google Cloud Storage.
• Device registration, as described above.
• App integrity. Firebase App Check uses Apple’s App Attest or DeviceCheck to confirm that requests come from a genuine copy of Audivision. Apple performs the check; we receive only the result.

Our servers keep a standard log of these requests, including your account ID, the time, and whether the request succeeded. We use these logs only to keep the service running and secure.

Usage statistics and crash reports

So that we can see which features are used and be told when the app breaks, Audivision sends usage statistics (Google Analytics for Firebase) and crash reports (Firebase Crashlytics) to Google, who process them for us. They are on from the first time you open the app. There is no setting in the app to turn them off; if you object, write to us.

• Usage statistics record which screens and tabs are opened; that you signed in, and that it was with Apple; that a page was read or exported, with its language; that a plan was selected or bought; that Help was opened; and errors, such as a failed purchase, a failed request to our servers or a failed database write, with a short error description. Google also records standard information such as your device model, iOS version, app version, the country and region derived from your connection’s IP address, and may record in-app purchases with their product and price. They are tied to a random identifier that Google generates for this installation, not to your name, email or account ID.
• Crash reports record what the app was doing when it crashed or hit an error, the kind of phone, its iOS version and app version, and its memory and storage state. They are not linked to your account.

Neither ever contains the content you read, scan or listen to.

What stays on your phone only

The following are processed and stored only on your phone (apart from the optional iCloud sync below), and are never uploaded to us or to our processors:

• photos, camera frames and scans, and documents, e-books and files you import or open in the app;
• the text recognised from them. Text recognition runs on your phone, using Apple’s and Google’s on-device technologies, and the app’s own models;
• the spoken audio. Speech is synthesised on your phone, either by the app’s own on-device speech synthesis or by the voices built into iOS;
• your library and folders, books you have downloaded, your wishlist, highlights, notes and bookmarks;
• your reading sessions, reading pace and Reading Insights, and your reading position; and
• your settings, such as voice, speed, reading appearance and tab order.

Your Apple Watch and widgets show information from the app on your phone. The watch talks to your phone directly through Apple’s Watch connection, not through our servers.

Optional iCloud sync. When Settings › Sync with iCloud is on (it is on by default if your phone is signed in to iCloud), your reading position, highlights, notes and bookmarks are also stored in the private database of your own iCloud account, so they appear on your other devices signed in to it. Apple stores them under Apple’s terms; the text of highlights and notes and your file names are encrypted with keys from your iCloud Keychain. We have no access to this copy. Your documents, photos, scans and the recognised text are never synced. You can turn sync off at any time; deleting your account also deletes the iCloud copy.

Like other app data, this information may be included in the iCloud or computer backups of your iPhone that you make, under Apple’s terms. Deleting your account erases it from the phone (see Deleting your account), as does deleting the app.

Other services the app uses on your phone

• Google ML Kit recognises text on your phone. Images and text are not sent to Google. Google states that ML Kit may contact Google’s servers to receive fixes and model updates, and to report how the library is performing.
• Voice input in Find mode uses Apple’s speech recognition. Depending on your device and language, Apple may process your voice on its servers under Apple’s privacy policy. The app receives only the text, uses it to search what the camera sees, and does not store or upload it.
• Web address import. If you import a web page, the app downloads it directly from the website you entered. We do not receive the address or the page.
• Update check. The app asks the App Store whether a newer version exists, sending only the app’s identifier.
• Email and community links. If you send us feedback by email, your email app sends it, including the app version, iOS version and phone model it fills in for you. If you open our Telegram group, Telegram’s own privacy policy applies.

Permissions

The app asks for these only when a feature needs them, and you can change each one in iPhone Settings › Apps › Audivision:

• Camera: to read text live and scan documents. Without it, the Library, Books and the reader still work.
• Photos: to import images you choose, and to save scans to your photo library.
• Microphone and Speech Recognition: for voice input in Find mode.

Audivision does not ask for your location, contacts or notifications, and it does not ask to track you.

Why we use your data, and on what basis

Where we rely on consent, you can withdraw it at any time by deleting your account or by writing to us. Withdrawing consent does not affect what was done before.

Who else sees this

We do not sell your data, and we do not share it with advertisers, data brokers or any other third party. These companies process it for us:

• Google, through Firebase and Google Cloud: Authentication, Cloud Firestore (our database), Cloud Functions, Cloud Storage, App Check, Google Analytics for Firebase and Crashlytics. Google acts as our processor under its Firebase data processing terms.
• Apple, for Sign in with Apple, App Attest and DeviceCheck, the App Store and in-app purchases. Apple handles your Apple Account and payment under its own privacy policy.

We may disclose information where the law requires it, or where it is necessary to investigate a breach of our terms or to protect someone’s safety.

Where your data is stored

Our servers run on Google Cloud in the United States (our server functions run in the us-central1 region, in Iowa). Google’s analytics and crash-reporting systems may process data in the United States and other countries. This means your data is transferred outside India and, if you live in the EU or UK, outside those regions. We rely on Google’s data processing terms, including the standard contractual clauses they incorporate, to protect it, and we transfer data only to countries the Government of India has not restricted.

How long we keep it

About these hashes. A hash is a short code calculated from a value, such as your email address, from which the value cannot be read back. Ours are a shortened SHA-256 hash with no secret key. Someone who already knows your email address or account ID could calculate the same hash and match it to these records, so we treat them as pseudonymous personal data, not as anonymous data. We use them only for the purposes above, and never to contact you or to rebuild a profile of you.

Deleting your account

Open the app menu, then About › Account details › Delete my account. You can tell us why you are leaving if you wish, then confirm with Sign in with Apple once more. If you cannot use the app, write to contact@audivision.in from the email address on your account and we will do it for you.

• On your phone, straight away: the app asks Apple to end its Sign in with Apple link to your Apple Account, signs you out, and erases your library, imported and downloaded files, highlights, notes, bookmarks, reading history, saved name and email, and protected-content keys from the phone, and deletes the iCloud sync copy (as soon as the phone is online). Books from the built-in catalogue list stay, because they are part of the app.
• For 30 days: your account is closed and marked for deletion, but kept, so that you can change your mind. Signing in again within 30 days cancels the deletion and restores your account.
• After 30 days: your sign-in account, profile record and setup answers are deleted, and the other records are reduced as described in How long we keep it. Our deletion job runs once a day, so this can take up to one more day.

Deleting the app on its own does not delete your account or the records on our servers. Deleting your account does not cancel a subscription: Apple bills it, so cancel it in your Apple Account settings. Your purchases belong to your Apple Account, and you can restore them after signing in again with a new account.

Security

All traffic between the app and our servers is encrypted. Our database is protected by access rules so that each signed-in account can reach only its own records, and our server functions accept requests only from genuine copies of the app. Google encrypts the data it stores for us. On your phone, keys are kept in the iOS Keychain, and the app’s files are protected by iOS data protection. No system is perfectly secure; if a breach affects your personal data, we will tell you and the Data Protection Board of India as the law requires.

Children

Audivision is not designed for young children and does not knowingly collect data from children under 13. If the person using Audivision is under 18, a parent or lawful guardian must agree to our terms for them and, by doing so, consents to the processing described in this policy. We do not track, profile or show advertising to anyone, including children. If you believe a child is using the app without that consent, write to us and we will delete the account.

Your rights

Whatever we hold about you, you are entitled to:

• See it: ask what we hold and why, and get a copy of it.
• Correct it if it is wrong or out of date.
• Have it deleted: see Deleting your account.
• Withdraw your consent, by deleting your account or by asking us.
• Object to or restrict how we use it, and receive it in a portable form, where the law gives you those rights.
• Nominate someone to exercise these rights for you if you die or become unable to.
• Complain: to our Grievance Officer first, and then, if we have not put it right, to the Data Protection Board of India, or to the data protection authority where you live.

Write to contact@audivision.in, ideally from the email address on your account. We answer within 30 days and never charge for it. We may need to confirm that the account is yours before acting on a request.

Changes to this policy

We will update the “Last updated” date above whenever this policy changes. If a change materially affects what we collect or how we use it, we will tell you in the app before it takes effect.
