How can we help?

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.

No. You can use LoveLust without signing up: no email, no password. If you want one, a LoveLust account keeps your Plus and your rewards with you, so you get them back on a new phone. It holds your email, the name and avatar you choose and how you sign in, never anything you log. Without an account, the app identifies itself to our backend with a random identifier that is not derived from anything you entered, so that notifications and purchases work.

LoveLust is for people aged 16 or over. If you're 16 or 17, content meant for adults is hidden, we don't collect intimate analytics or send you marketing, and any purchase needs a parent's or guardian's permission.

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, which is also why LoveLust works without internet. It reaches Apple Health or Health Connect only if you turn that integration on.

What does leave the device is limited and never intimate: an internal identifier, your language, your notification token, the app version, your subscription status and your communication preferences, plus crash diagnostics, and anonymous analytics that stay off until you agree. A survey answer leaves only if you choose to answer one, and is stored without any identifier. The Privacy Policy has the full detail, including the Firebase SDK we are working to remove.

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. A partner in LoveLust is a private note you keep for yourself. Nothing is sent to them, they are not invited, they have no account, and there is no way for one person's app to see another's. Anything you save about someone else stays on your device under the same encryption as the rest.

In the app: Settings → Storage → Clear all data erases everything on the device, and asks our backend to delete your account record at the same time. Uninstalling the app also removes local data, but leaves that record. If you have a LoveLust account, you can delete it from the account website.

Important: if you used cloud backup, clearing local data or uninstalling does not delete the backup. To remove it, go to Settings → Cloud storage, sign out, and delete the remote backup. We keep it until you do, so you can restore after reinstalling.

You can also access, correct, export and restrict your data, and withdraw consent in Settings → Privacy without deleting anything. For any of your rights, write to [email protected]; we reply within 30 days.

Yes, with the encrypted cloud backup, a Plus feature that doubles as sync. Your data is encrypted on your device with a key derived from a passphrase you choose, then uploaded to your own Google Drive or iCloud; we never receive the backup or the passphrase. Enable it on the first device, then sign in and enter the same passphrase on the second. Without it, each device keeps its own separate data.

With the encrypted cloud backup, you restore everything on a new phone with your passphrase. Without it, your data lived only on that phone and is gone, so we recommend turning the backup on in Settings.

We cannot recover a lost passphrase, and we cannot decrypt a backup without it: that is the point of the encryption. Keep it somewhere safe.

Cancel anytime in your App Store or Google Play subscription settings. Cancellation takes effect at the end of the current billing period. Deleting the app does not cancel your subscription. Refunds are handled by Apple or Google under their policies.

Nothing is deleted, and nothing is held hostage. Your data stays on your device exactly as it is, you can still log, and you can still export all of it. The Plus features stop, so some readings and screens go back behind the offer, and the encrypted cloud backup stops updating. Subscribe again and everything is where you left it.

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.

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.

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.
