Charbonnance is made by Charley Guillot, who is the data controller for the personal data described here. For any question or request about your data, write to support@charbonnance.com.
Your account: your email address, a display name and your password (stored only as a hash by our authentication provider).
Your training: the routines you write, the workouts you log (exercises, sets, reps, weights, times, distances, notes, pauses and timer scores), the personal bests worked out from them, and any exercises you create.
When you accepted this policy and which version.
Your subscription status (Pro or free, the product and its expiry date). Payments are handled by the Apple App Store or Google Play; we never see your card details.
We do not collect your location, contacts, photos or health records, and we ask for no information about your body.
We use this data only to provide the app: to keep your account, your plans and your history, and to show your progress. The legal basis is the performance of the contract you enter into by creating an account (GDPR article 6(1)(b)).
To run the Pro subscription we record, through RevenueCat, which purchase you made, so that the app can unlock Pro features. The legal basis is the same contract.
Free accounts show advertising (see below). The legal basis for personalised advertising is your consent (GDPR article 6(1)(a)), which you can withdraw at any time.
We run no analytics of our own, and your data is never sold or shared for marketing.
Free accounts show ads provided by Google AdMob: banners on the Today, Routines, Exercise Library and Progress screens, and at most one full-screen ad a day after you finish a workout. There are never ads while you log a workout, on a timer, or for Pro accounts.
To show and measure ads, Google may use your device's advertising identifier, your IP address and information about the ad shown. Your routines, workouts and account details are never sent to Google or to advertisers.
In the European Economic Area, the United Kingdom and where else the law requires it, the app asks for your consent before any ad is requested. On iPhone it also asks Apple's permission to track. If you refuse, you may still see ads, but they are not personalised.
You can review or withdraw your choice in Account → Ad privacy choices, in your phone's settings (on iPhone, Privacy & Security → Tracking), or by resetting your advertising ID. Upgrading to Pro ends all advertising.
Your data is stored by Supabase, our database and authentication provider, on servers in Zurich, Switzerland, a country the European Commission recognises as giving adequate protection. Supabase acts only on our instructions under a data processing agreement; as a US company it relies on the EU standard contractual clauses for any access from outside Europe.
RevenueCat, Inc. (United States) processes purchase information for the subscription, linked to your account identifier. Google Ireland Ltd. and Google LLC provide the advertising described above to free accounts. Both rely on the EU standard contractual clauses or equivalent safeguards for transfers outside Europe.
Reminders such as the rest timer and the "workout still running" alert are scheduled on your device and never leave it.
For as long as you have an account. When you delete your account, everything listed above is deleted at once and cannot be recovered. Copies may persist in our provider's backups for a short period until those backups expire.
You can see and correct your account details in the app (Today → Account), export all your data as a file (Account → Export my data) and delete your account and all its data (Account → Delete account).
You can also ask, by writing to support@charbonnance.com, for access to your data, its correction or deletion, a copy in a portable format, or to restrict or object to its processing. If you no longer have the app, you can ask for your account to be deleted the same way, from the address you signed up with. We answer within one month.
If you think your data is mishandled, you can complain to the CNIL (cnil.fr), the French data protection authority, or to the authority of the country where you live.
If this policy changes, the app tells you and asks you to read and accept the new version.
