The private sexual health journal: activity, partners, cycle, STI tests and medication, encrypted on your phone.

LoveLust is a private sexual health journal for iOS and Android. It logs sexual activity and partners, follows the menstrual cycle, keeps track of STI tests, PrEP and other medication, and shows statistics, with games for couples and parties. Everything logged stays on the phone, encrypted.

LoveLust is free to download and use. LoveLust+: All games unlimited, deeper cycle insights, statistics by partner and date range, encrypted cloud sync with Apple Health or Health Connect, the biometric app lock, and the themes and alternate icons. Everything else, including logging, reminders, screenings and the basic cycle tracking, is free.

Yes. Your sexual activity, partner, cycle, medication and health data is stored locally on your device, in encrypted storage, and is never sent to LoveLust servers, never sold, and never shared with advertisers. Cycle predictions, safety readings and statistics are all calculated on your device. It is shared with Apple Health or Health Connect only if you turn that integration on. See the Privacy Policy for full detail.

No. There is no sign-up, no email, no password. The app identifies itself to our backend with a random identifier that is not derived from anything you entered, and that exists so notifications and purchases work. Nothing you record is tied to a name.

That is what these settings are for:

• App lock (Plus) requires your face, fingerprint or a PIN before the app opens.
• Discreet notifications strips reminders down so a lock screen shows nothing about what they concern.
• Alternate app icons (Plus) let the app sit on your home screen under a different look.

Two things to be aware of: an iOS widget or watch complication shows what it shows to whoever glances at the screen, so choose which one you place; and anything you export, such as a PDF report, is an ordinary file once it is saved or shared.

No. LoveLust is not a contraceptive, not a fertility treatment and not a medical device. The fertile window is an estimate drawn from what you logged, it can be wrong, and it must never be the reason you skip protection. For contraception or family planning, talk to a healthcare professional.

Only if you turn it on, and you choose the direction. With the integration enabled, cycle data can be read from and written to Apple Health on iOS or Health Connect on Android, so LoveLust and the rest of your health apps agree. Turning it off stops the exchange; what was already shared lives in that health app, under its own controls.

Yes. Everything you have recorded exports as JSON from Settings → Storage → Export data, on any plan. LoveLust+ also builds a PDF report for a consultation, covering your cycle, screenings, medication and the relevant history, and deliberately leaving your partners out of it: no partner name, no partner id, nothing read from a partner's record.
