Who is responsible
The app “Kyklaki” is run by: Ant Du, contact email: sonikplus93@gmail.com
What data we keep
- From your Google account: name and email, only to sign you in.
- What you enter yourself: period dates, period and cycle length and, if you fill them in, symptoms, mood, sexual activity, weight, temperature, birth control pill intake, pregnancy and notes.
- If you turn on notifications: an identifier of your device so we can send them, and your time zone.
Cycle data is considered health data. We process it only with your explicit consent, which you give during the first setup.
Why we use it
Only to show you your calendar, your predictions and, if you turn them on, reminders. We do not sell it, we do not use it for advertising and we do not share it with third parties.
Where it is stored
In Google Firebase. Only you, signed in with your account, can access your data.
Your rights
- You can change or delete any entry at any time.
- In Options → “Delete all my data” your data and your account are permanently deleted. This also withdraws your consent.
- For any request (access, a copy, correction) write to sonikplus93@gmail.com. You also have the right to complain to your data protection authority (in Greece: dpa.gr).
Important
Predictions are estimates based on the average of your cycles. They are not medical advice and not a method of contraception.
