Frequently asked questions

SyncHer is an app for boyfriends and partners. You enter when her last period started and her usual cycle length, and SyncHer shows an estimated cycle phase with one simple, thoughtful action for the day. Wingman, the raccoon wingman, keeps it light and practical.

SyncHer counts forward from the start date you enter using her average cycle length. It splits the cycle into four color-coded phases: Period (red), Recovery (blue), Green zone (green) and PMS window (yellow).

It's an estimate. Real cycles vary, so update the start date when her next period begins — there's a one-tap “Her period started today” button on the home screen.

No. SyncHer is a relationship and communication aid. It doesn't diagnose anything, predict ovulation for contraception or pregnancy, or replace advice from a doctor. If there are health concerns, talk to a healthcare professional.

No. The phase guide describes common patterns, and plenty of people don't match them. Use it as a reminder to pay attention, and always go by what she actually tells you.

Chat is a conversation with Wingman. Describe what's going on — “she said she's fine but she seems upset” — and Wingman replies with ideas and, when it helps, a line you could say. Ask follow-up questions as the situation changes. Treat suggestions as a starting point and put them in your own words.

No. SyncHer is designed for you. We do recommend being open with her about it — most people appreciate a partner who pays attention.

iPhone comes first. An Android version is planned.

No. There's no sign-up, email or password.

Her nickname, the dates you enter, her cycle length, favorites, notes and your goals are stored on your phone. Built-in tips and daily notifications are generated on your phone.

AI tips are optional: SyncHer asks during setup and sends nothing until you say yes. When they're on, they send only what's needed to write a tip: the current phase and cycle day, the favorites you picked, a short summary of which tips worked, the day of the week, and the recent messages of your Chat conversation.

Her name, the actual dates and your contact details are never sent. The request goes through SyncHer's server in the EU to an AI model provider that is configured not to keep or train on the data. Full details are in the Privacy Policy.

Yes, anytime in Settings → AI tips. With AI tips off, SyncHer uses tips built into the app and nothing is sent to the AI service.

Go to Settings → Delete all data. This erases everything SyncHer stored on your phone and signs out the anonymous AI session. Deleting the app also removes the data on your phone. Subscriptions are managed by Apple and are not cancelled by deleting data — see below.

SyncHer offers monthly and yearly subscriptions. The exact price in your currency is shown in the app before you subscribe.

Eligible new subscribers get a 3-day free trial. If you don't cancel at least 24 hours before the trial ends, the subscription starts and your Apple account is charged. Whether you're eligible is decided by the App Store.

On iPhone, open Settings → your name → Subscriptions → SyncHer, then Cancel Subscription. You keep access until the end of the current billing period.

Payments are processed by Apple, so refunds are requested through Apple at reportaproblem.apple.com.

Sign in with the same Apple account, open SyncHer and tap Restore on the subscription screen or in Settings. Your cycle data isn't synced between phones, so you'll need to enter it again.
