Privacy policy

Last updated: 21 August 2026.

In short

VoiceTag works without an account: there is no username or password to create.

Your voice memos, your written memos and the link between your labels and their content stay on your phone. They are never sent to us.

The app connects to the internet in one case only: when you consult a label placed by an organisation — a museum, a shop, a public service. It then fetches the content of that label and records that a consultation took place, without anything that could identify you.

There is no advertising, no tracker, no audience measurement and no sale of data.

Who is responsible for this data

The data controller is Nicolas Lacourte-Barbadaux, sole trader, operating under the business name Un miro dans la ville.

3 rue du faubourg Bannier 45000 Orléans France

SIREN number: 983 917 105.

What stays on your phone

Everything you create with VoiceTag is stored in the app’s private storage area, on your device:

• your sound recordings;
• your written memos;
• the link between each label and the content you attached to it;
• your settings, such as language or reading speed.

We have no access to any of it. This information leaves your phone only if you decide to share it yourself, and it disappears if you uninstall the app.

Backups

VoiceTag can gather your memos into a backup file. That file is created on your phone, and you then choose what becomes of it, through your system’s usual sharing menu: email it, put it on a storage service, or keep it on the device.

The file is never sent to us, and we do not know where you send it. Once it has left your phone, it is governed by whichever service you entrusted it to.

What is sent over the internet

In which case

Only when you consult a label placed by an organisation.

If you use VoiceTag solely with your own labels, the app connects to no server at all. It opens no connection on startup.

What is read

The content of the label being consulted: the texts written by the organisation, the sound files it may have uploaded, along with its name and logo.

This request transmits nothing about you. It simply asks for the content attached to a label identifier.

What is recorded

So that organisations can tell whether their labels are being used, four pieces of information are recorded on each consultation:

• the label identifier;
• the organisation identifier;
• the language the content was shown to you in;
• your phone’s system, iOS or Android.

That is all. No device identifier, no account number, no name, no location. Two consultations made from the same phone cannot be linked to one another, neither by us nor by the organisation.

As with any connection to a server, the hosting provider sees the IP address of your connection and keeps it for a few days in its technical logs, for security and diagnostic purposes. That address does not appear in the consultation statistics passed on to organisations.

Where this data is hosted

On Supabase servers, in their Paris region, in France. It does not leave the European Union.

Purchases

The subscription and the one-off purchase go through Apple’s App Store or through Google Play, depending on your phone. Apple or Google collects the payment and handles your billing.

VoiceTag sees neither your payment method, nor your name, nor your address. The app only receives confirmation from the app store that your purchase is valid.

The processing of your payment data is therefore governed by Apple’s or Google’s own privacy policy.

Reading aloud

When VoiceTag reads a text aloud, it hands that text to the speech synthesis engine installed on your phone.

Depending on the engine selected in your system settings, that speech may be produced on the device or on its publisher’s servers. This does not depend on VoiceTag but on your system and on the engine you have chosen.

What VoiceTag does not do

• No user account, no sign-up.
• No advertising and no advertising tracker.
• No audience measurement tool and no analysis of your behaviour in the app.
• No automatic crash report.
• No access to your location.
• No data sold, rented or passed to a third party for commercial purposes.

Permissions requested

• Microphone: to record your voice memos. If you refuse it, written memos remain usable.
• NFC: to read and write your labels.
• Internet access: to consult organisations’ labels and to verify your purchases.
• Vibration: to signal by a vibration that a label has been recognised.
• Files and photos: only to locate a backup file you want to import back. The app does not browse your library.

How long data is kept

What your phone holds stays there until you delete it, and disappears when you uninstall the app.

Consultation statistics are kept for twenty-five months. This is the period recommended by the French data protection authority for this kind of measurement.

The hosting provider’s technical logs are kept for a few days.

Your rights

The General Data Protection Regulation gives you a right of access, rectification, erasure, objection and portability over data concerning you. You may exercise these at the address given above.

One honest point here: the consultation statistics contain no identifier relating to you. We are therefore unable to find within them anything that came from your phone. That is a direct consequence of the choice to collect no identifier, not a refusal to answer you.

If you believe your rights are not being respected, you may lodge a complaint with the French data protection authority, at cnil.fr.

Changes to this policy

Any change will be published on this page, and the last-updated date at the top of the document will be corrected. If a change were to broaden what is collected, it would be announced in the app before taking effect.
