Nothing. Sielle has no accounts, no sign-up, no analytics, no advertising, no tracking of any kind, and no third-party software. The app's App Store privacy label is "Data Not Collected".
Everything you log — symptoms, hot flashes, medications, notes, questions — is stored in a local database on your device only.
Sync is off by default. If you turn it on, your diary is mirrored to your personal, private iCloud database, encrypted in transit and at rest by Apple. Only your Apple ID can access it; the developer has no access. Turn it off anytime in More → iCloud sync. Apple's handling of iCloud data is described in Apple's privacy policy.
If you choose to connect Apple Health, Sielle reads sleep, resting heart rate, heart rate variability, steps, and mindful minutes — read-only — to display them next to your logs. Sielle never writes to Health and never transmits Health data anywhere. The app works fully without Health access.
Subscriptions are handled entirely by Apple through your App Store account. We never see your payment details. Apple provides us no personally identifying information about you.
Khomenko Denys Dmytrovych, vul. Nasonova 12, Kostiantynivka, Cherkasy raion, Cherkasy oblast, Ukraine · homasglobal443@gmail.com. Because the app keeps your diary on your device, we never receive, see, or store your health information — there is nothing on our side to request, correct, or delete.
These pages set no cookies, run no scripts, and load nothing from third parties — which is why you see no cookie banner: there is nothing to consent to. Our hosting provider keeps standard technical server logs (IP address, time, page requested) for security and operation of the service (legitimate interest, GDPR Art. 6(1)(f)); logs are routinely deleted and not used for profiling.
When you write to support, we process what you send (your email address and message) solely to answer you (GDPR Art. 6(1)(b)/(f)). Please don't include health details in support emails — we don't need them to help with app issues. Correspondence is deleted once your question is resolved, at the latest after 12 months.
Under the GDPR (and similar laws such as the UK GDPR and CCPA) you have the right to access, correct, delete, and receive a copy of personal data a company holds about you, and to object to its processing. For your diary these rights are built into the app itself (Export / Delete all data) because the data never leaves your device. For support correspondence, email us and we will act on your request. You also have the right to complain to your local data-protection authority.
Sielle is intended for adults and is not directed at children under 13.
If this policy ever changes, the updated version will be posted at this address with a new date. The local-only principle is the product — it is not going to change.
