How privacy works
✓ Private by design
✓ Sharing stays under your control
✓ Estimates show uncertainty
For adults. Cycle estimates are not medical advice and must not be used for contraception, fertility planning, diagnosis or medical decisions.

One app. Four ways to use it.
Kitho asks what you want to do — not who you are. Start with the experience that fits your life and change it later in Settings.
My partner
Keep useful relationship context together and see cycle information only where your partner has chosen to share it.
Both
Use Kitho for your own cycle and to support a partner without mixing private and shared information.
Relationships only
Use partner profiles, important dates, reminders and private context without cycle tracking at all.
Useful context, without false certainty.
Cycle timing changes. Kitho turns recorded history into explicitly labelled estimates and makes uncertainty visible instead of hiding it behind a single exact date.
Your cycle
A private cycle view built around your own data.
Record period starts and ends, optional ovulation dates, bleeding intensity, symptoms and private notes. The self-managed experience keeps personal details separate from anything a connected supporter can see.

Supporting someone
Shared context without turning a relationship into surveillance.
Connected partners see only the categories the self-managing person allows. Period timing, fertile phase, ovulation estimates and current cycle status can be controlled separately.

Apple Health, read-only
Import menstrual-flow records and positive ovulation-test results after explicit permission. Kitho never writes back.
Thoughtful reminders
Configure notifications around predicted menstruation, menstruation end and ovulation, including discreet wording.
Calendar sync
Optionally add selected Kitho dates to your device calendar while checking for existing dates.
Relationship memory
Keep partner profiles, important dates, notes and private context together so useful details are easier to remember.

Privacy by design
Your data. Your decisions.
Kitho is built around clear data boundaries. Apple Health-derived observations and estimates stay in the self-managed experience and are excluded from supporter views. Kitho does not use cycle data to infer mood, behaviour, pregnancy or contraception status.
No tracking declarationKitho does not currently ship a third-party crash-reporting SDK and does not declare tracking.
Permission when neededContacts, calendar, photos, notifications and Apple Health are requested only for the feature you choose to use.
Export and deleteExport your Kitho data in-app and permanently delete your account from Settings.
“Cycle awareness should help people be more thoughtful — never more intrusive.”
A relationship tool, not a scoring system.
Kitho is designed for relationship awareness and self-managed cycle tracking. It is not a medical device, fertility tool, surveillance system or relationship-scoring app.
Questions, answered plainly.
The important boundaries should be understandable before you create an account or share sensitive data.
Can Kitho be used only for my own cycle?
Yes. You can use a self-managed cycle profile without adding or inviting a partner.
Does Kitho predict exact dates?
No. Kitho shows estimates and confidence based on available history. Future timing becomes less certain the further out the forecast goes.
Can a partner see my symptoms or private notes?
No. Optional symptoms, bleeding intensity and private cycle notes are not exposed to supporter accounts.
Does Kitho write to Apple Health?
No. Apple Health integration is read-only and limited to menstrual-flow records and positive ovulation-test results after permission.
Can I delete my data?
Yes. Account deletion is available in Settings → Account → Delete Kitho account. A web deletion route is also available if you cannot access the app.
Is Kitho medical advice?
No. Estimates must not be used for contraception, fertility planning, diagnosis or other medical decisions.
More understanding.
Brighter days.
