Terms of use and data handling for the Partie Double iOS app.
“Partie Double” iOS app · Last updated: August 2026. This page mirrors the terms shown in the app (Settings › Legal). Contact: partiedouble.administrateur@gmail.com. In short: your data stays stored on your device; your financial data (net worth, budget, calculators) is never used and only ever leaves your device end-to-end encrypted, if you enable synchronisation across your devices; your data is never sold, nor shared for commercial or advertising purposes; you can delete your account and all your data directly in the app (Settings › Account management).
This agreement governs the use of the Partie Double app and the handling of its users' personal data. By creating an account, you acknowledge that you have read and accepted these terms.
For any question about your data or the exercise of your rights, a single contact is available: partiedouble.administrateur@gmail.com.
The service is available to people aged 15 and over. Below 15, sign-up requires the consent of a parent or legal guardian. You agree to provide accurate information and keep it up to date, to keep your credentials confidential, and to use a single account for strictly personal purposes.
We store the information you enter at sign-up (first name, last name, email, institution, programme or situation, level or year, age range, city, country, status, and for teachers the programmes and years taught), your referral code and, where applicable, the code of the person who invited you, as well as usage data linked to your progress (serious-game missions, training sets completed, paths followed). We also store the information you enter in the simulators and net-worth tracker (characteristics and estimated value of your property, ownership shares, amounts of savings, investments and loans, and calculator inputs). The app also performs anonymous usage measurement: a random install identifier, the duration and frequency of your sessions, the screens and features used, and non-identifying attributes (status, language, country). When online accounts are introduced, the sign-up information and usage data described above will be collected by the publisher under the terms of this agreement. The financial data you enter in the net-worth tracker, the budget and the calculators stays, by default, only on your device. If you enable synchronisation across your devices, your budgets, trip budgets and net-worth tracker are end-to-end encrypted on your device and then kept only in that encrypted form on our synchronisation service (hosted within the European Union): the publisher holds no decryption key and can therefore never read or use them. Calculator data, for its part, never leaves your device. No banking details (card number, IBAN) are collected or stored by the publisher.
This data is used to personalise your tracking and revision, tailor content to your programme, provide the financial simulation and net-worth tracking features you use, run the referral programme, and improve the app through anonymous, aggregated usage statistics (audience measurement). It is used for no other purpose: it is never sold, rented, transferred or exploited for commercial or advertising purposes, whether by the publisher or by third parties. The financial data in the net-worth tracker, budget and calculators only serves your own calculations, on your device. You may object to this processing at any time (see the “Your rights” article).
Processing is based on your consent, collected at sign-up, and on the publisher's legitimate interest in operating and improving the service. You may withdraw your consent at any time, without affecting the lawfulness of processing carried out beforehand.
Your data is intended for the publisher. It may be processed by technical providers acting on its behalf and bound by confidentiality and security: the app's distribution and payment platform (Apple), the host of the device-synchronisation service located within the European Union (Supabase; data is stored there only in end-to-end-encrypted form, unreadable by it or by the publisher), the host of online accounts located within the European Union (once online accounts are offered), the subscription-management provider and an anonymous audience-measurement tool. Some features may in the future be offered as a paid subscription: terms and prices will be shown before any purchase, and the core app will remain free. Any payments (subscriptions) are handled by Apple; the publisher receives no banking data. No other recipient receives your data: it is never passed on to any commercial partner, advertiser or data broker.
By default, your data is stored only locally, on your device. If you enable synchronisation across devices, your budgets, trip budgets and net-worth tracker are hosted, in end-to-end-encrypted form only, on a synchronisation service located within the European Union; you can erase them from that service at any time from within the app. When online accounts are introduced, other data will be securely hosted within the European Union, with calculator data remaining stored only on your device. It is kept while your account is active, then deleted or anonymised within a reasonable time after the account is closed or upon your request.
Your data is not exploited commercially in any way. It is never sold, rented, exchanged or transferred to third parties, and it is never shared with any commercial partner, advertiser, ad network or data broker, for prospecting or targeting of any kind. It is passed only to the technical providers listed in article 7, which act on the publisher's behalf and may not use it for their own purposes. The only messages you receive are, where applicable, the app-related information you agreed to receive by email (article 10), sent by the publisher alone. The financial data in the net-worth tracker, budget and calculators is never shared in any event: when synchronised, it travels only in end-to-end-encrypted form and remains unreadable by the publisher. No transfer outside the European Union takes place without appropriate safeguards. Should this policy ever change on this point, your prior and explicit consent would be sought, and you could refuse it without losing access to the service.
With your consent (optional box at sign-up), your email may be used to send you information about the app: new features, content updates, revision tips and project news. You may withdraw this consent at any time, via the unsubscribe link in each email or by contacting us. This choice is independent of creating your account.
As a native app, Partie Double uses no cookies (a web-specific mechanism) and no advertising or third-party tracking tools for targeting. It performs anonymous usage measurement (a random install identifier, session durations, screens and actions), kept locally on your device. Sharing these statistics with the publisher, once enabled with online accounts, is subject to your prior consent, revocable at any time in the app (Settings › My usage). The app contains no advertising to date; if advertising were introduced in the future, this policy would be updated beforehand and, where applicable, your consent to ad tracking would be requested in line with Apple's rules (App Tracking Transparency).
Reasonable technical and organisational measures are in place to protect your data against loss, alteration or unauthorised access. In the event of a breach likely to result in a high risk to your rights, you will be informed and the competent authority notified, in accordance with the regulation.
In accordance with the GDPR, you have the right to access, rectify, erase, restrict, port and object, as well as the right to withdraw your consent and to set instructions on the fate of your data after your death. You may exercise these rights by email at the contact provided. You may also lodge a complaint with the relevant supervisory authority (in France, the CNIL).
The app, its brand, educational content, texts, visuals and databases are protected and remain the property of the publisher or its partners. You are granted a personal, non-exclusive right of use limited to private use. Any unauthorised reproduction, distribution, resale or exploitation is prohibited.
You agree to use the app in good faith and not to disrupt its operation: no attempt at unauthorised access, circumvention of protections, mass extraction of content, or use contrary to the law or these terms.
You may close your account and stop using the app at any time. The publisher may suspend or terminate access in the event of a serious breach of these terms. Closing the account results in the deletion of the associated data, subject to legal retention obligations.
The app is provided “as is”. The publisher strives to ensure its availability but does not guarantee uninterrupted or error-free operation, and may change or suspend the service for maintenance. It cannot be held liable for indirect damages arising from use of the app.
The app offers educational content for information purposes, with no guarantee of completeness or absence of error. It does not constitute personalised professional advice (accounting, legal, tax or financial).
These terms may be updated. In the event of a substantial change, you will be informed and a new acceptance may be requested.
This agreement is governed by French law. In the event of a dispute, an amicable solution will be sought first; failing that, and for consumers, a consumer mediator may be referred to. French courts have jurisdiction under the conditions provided by law.
