No. TsukiLift works fully without an account. It never asks for an email address or any personal details.

It is optional. If you decline or skip HealthKit integration, you can still use every feature of the app, including period logging, workouts, BBT, body composition, and symptom logs. You can change the setting at any time under "Settings → HealthKit Integration".

Only on your iPhone. Nothing is ever sent to an external server or the cloud. iCloud sync is not used either, so moving to a new device requires a manual export and import.

Yes. Save a JSON file from "Settings → Data Management → Export", then import that file on the new device. This feature is free.

The app averages your past records to estimate your cycle length and predict the next start date. Accuracy is lower when there are few records. It is a reference trend, not a medical diagnosis.

No. This app is not a tool for identifying ovulation or for contraception or pregnancy decisions. What it shows are cycle trends, and it cannot be used for medical decisions. Please consult a doctor or another qualified professional for those purposes.

If you turn on "Settings → Using hormonal contraception", a note is shown alongside cycle phase predictions to indicate that they are reference values. Because hormonal contraception changes the cycle, prediction accuracy may be lower than usual.

Yes. In addition to the built-in exercise catalog, you can add your own. Creating and saving workout templates lets you recall your favorite exercise sets quickly (unlimited templates are a Premium feature).

The app applies a common estimation formula to your logged set data (weight, reps, RPE). It is a reference value and may differ from your actual one-rep max.

From "Settings → Data Management → Export" you can export all data as JSON or CSV. Keep the exported file somewhere safe of your choosing (iCloud Drive, the Files app, and so on). This feature is free.

You can do that from "Settings → Data Management → Delete all data". This action cannot be undone, so we recommend exporting a backup first.

Yes. Because data is stored locally on your device, deleting the app erases all of it. Please export a backup before uninstalling.

All logging features — period, workouts, BBT, body composition, and symptom logs — plus the calendar view and data export and import are free. Premium adds advanced analysis reports and unlimited workout templates.

On your iPhone, go to "Settings" → "Apple ID (your name)" → "Subscriptions" → "TsukiLift" → "Cancel Subscription". Cancellation takes effect from the next renewal date. Deleting the app alone does not cancel the subscription.

Refunds for App Store purchases follow Apple's policy. Please request one via Apple's support page (reportaproblem.apple.com). We are not able to process refunds directly.
