Privacy Policy

OneFolder app · Last updated: 9 September 2026

This is an English translation of the French original. In case of conflict, the French version prevails.

This privacy policy describes how OneFolder (“the Application”, “we”) collects, uses, and protects your personal data, in accordance with the General Data Protection Regulation (GDPR) and the French Data Protection Act (loi Informatique et Libertés).

1. Who is the data controller?

The controller of personal data collected via the OneFolder mobile application (“the Application”) is:

Julien Cochard, publisher of the OneFolder application
Contact: contact@onefolder.fr

2. What is OneFolder?

OneFolder is a mobile app that lets you scan, organize, annotate, and export invoices and receipts. Access to the cloud service requires an account created with an email address (sign-in with a one-time code).

3. What data do we collect?

Depending on how you use the Application, we may process the following categories:

We do not intentionally collect bank payment data beyond what appears on the documents you choose to import. OneFolder does not include advertising. A third-party error-diagnostics tool (Sentry) is used for service reliability, as described below; it is not an advertising or marketing-profiling tool.

4. For what purposes?

5. Legal bases (GDPR)

6. Where and how is your data stored?

7. OCR analysis (Mistral)

When you start analyzing an invoice, the relevant images are transmitted securely to a OneFolder server function (hosted on Supabase), which calls Mistral AI’s OCR / extraction service in order to pre-fill certain fields (merchant, address, date, amount).

Images and text from OCR are processed solely for this extraction purpose. The Mistral API key is not embedded in the mobile app; it is kept on the server.

Provider: Mistral AI (a company established in France / the EU). For more information, see Mistral’s documentation and privacy policy.

8. Error diagnostics (Sentry)

To detect and fix Application crashes and errors, we use Sentry (Functional Software, Inc.), configured on Sentry’s European infrastructure.

In particular, we transmit: device type, operating system, Application version, technical error traces, and aggregated reliability indicators (for example the result of an OCR analysis: fields filled, no fields, or failure). We do not knowingly send invoice images, OCR text, or detailed invoice content to Sentry.

For more information: Sentry’s privacy policy.

9. Recipients and processors

In the course of the service, your data may be processed by:

We do not sell your personal data. We do not share it with advertisers.

10. Transfers outside the EU

We favor hosting in the EU (Supabase West EU; Sentry project configured on the European region). Some processors may carry out processing or technical support involving transfers outside the EU. In that case, appropriate safeguards (standard contractual clauses or equivalent mechanisms) are put in place with the providers concerned.

11. Retention periods

You can sign out at any time from the Application. Signing out ends the cloud session; it does not automatically delete content already synced to our servers. Deleting your account, available in the Application, results in deletion of your data within the timeframes stated above.

12. Your rights

Under the GDPR, you have, as applicable, rights of access, rectification, erasure, restriction, objection, portability, and the right to lodge a complaint with the CNIL (or the authority in your country of residence).

To exercise your rights: contact@onefolder.fr

13. Security

We implement reasonable measures to protect your data: code-based authentication, per-user cloud access controls, private storage of invoice photos, server-side storage of API secrets, and secure storage of sessions on the device. No system is infallible; we encourage you to protect access to your phone and email.

We do not access the content of your invoices and photos, except at your request as part of support, or where required by law or by the security of the service.

14. Children’s data

OneFolder is not intended for children under 16. If you believe a minor has sent us data, contact us for deletion.

15. PDF / Excel exports

Exports are generated on your device (temporary files / cache) and opened with system tools. Any later transmission (email, messaging, personal cloud) is your responsibility and governed by the services you use.

16. Changes

We may update this policy. The update date will appear at the top of the document. In the event of a material change, we may inform you in the Application or by email.
