Privacy policy
The first part is, word for word, the policy built into the app (Settings › Help and about › Privacy). The second part completes it for this public page.
In short
Your data stays on your iPhone. No account, no ads, no trackers, no selling.
The app’s policy
What the app processes, on your iPhone
Your doses (date, time, logged dose, injection site, lot number), your successive treatments, your weight, height and measurements, what you note in My health, the water, protein, steps and workouts you log, how you feel, your symptoms, warning signs and notes, your questions for the doctor, your appointments and expenses, your settings. This data is only used to show you your tracking, your reminders and your trends.
Apple Health
If you choose, the app reads your weight, waist, steps and workouts from the Health app, and writes there the weight, waist, water, protein and workouts you log here. You manage this access in the Health app.
What leaves your iPhone
Nothing, except what you export or share yourself. Tilde+ purchases go through Apple, which doesn’t pass on your name or your email address. Your iPhone backups follow Apple’s rules.
Safety
Your journal is protected by your iPhone’s encryption. You can lock it with Face ID or your passcode, and it’s hidden in the app switcher.
Retention and deletion
Your data stays as long as you keep it. Settings › Apple Health and backup › Erase everything deletes it from this iPhone; you can also erase what the app wrote to the Health app. Backups already made may still contain it until they’re replaced.
Minors
Tilde is for people aged 18 or over.
In addition
Who is responsible
Tilde is published by Benjamin Mongin, a sole trader established in France (details in the legal notice). For any question about your data: contact@benjaminmongin.fr.
As your data stays on your iPhone, the publisher has no access to it: he doesn’t receive it, doesn’t store it on any server and doesn’t process it.
Tilde+ and the App Store
Tilde+ (a monthly or yearly subscription with a free trial, or a lifetime purchase) is bought only through the App Store. Apple processes the payment under its privacy policy and doesn’t pass on your name or your email address.
You manage or cancel a subscription in your Apple Account settings (in the app: Settings › Tilde+ › Manage my subscription). Apple’s standard licence agreement applies.
Your rights
The GDPR gives you the right to access your data, correct it, erase it, restrict its use, object to it and take it with you (portability). As it is only on your iPhone, you exercise these rights yourself, in the app, without asking anyone:
Access and portability: Settings › Apple Health and backup › Export my data. The export opens in Excel or Numbers.
Correction: edit or delete an entry directly in the app.
Erasure: Settings › Apple Health and backup › Erase everything. What the app wrote to the Health app can be erased from Health › Sharing › Apps › Tilde.
The publisher holds none of your journal’s data: there is nothing to access or erase on his side. If you write to contact@benjaminmongin.fr, your address and your message are only used to reply to you; ask for them to be deleted whenever you like.
You can also lodge a complaint with the CNIL (the French data protection authority) or with the data protection authority of your country.
