Sync vs Period Pal

Sync Period tracks cycles locally and supports private sharing with a partner or friend. Log periods, symptoms, moods, and notes; view your calendar and pattern summaries; set optional reminders; and import supported Flo, Clue, Drip, or generic CSV data after reviewing what Sync can recognize. Your cycle history is encrypted on your device. Private predictions adapt to your recent cycle history and confirmed corrections entirely on your device. Sync shows a likely-start window and confidence level, learns recurring pre-period patterns, and can use an enabled BBT signal or positive ovulation test without uploading those health details. Predictions become more cautious when history is sparse or variable. Partner sharing is optional and off by default. You choose which supported cycle details to share. Updates are end-to-end encrypted and require the complete private invite to open. Each encrypted relay update expires after no more than 30 days; active sharing renews that rolling expiration when a new update is published. Recent physical symptoms and flow, sex-drive and intimacy check-ins, and moods are three separate opt-ins that can each be turned off again. Intimate sharing is off by default and never indicates consent. Discharge, medications, written notes, and other sexual details remain private. Sync Period has no ads, no behavioral analytics SDKs, and no required account. You can export a private backup or permanently delete local app data at any time. Cycle predictions and pattern summaries are estimates. Sync Period does not provide diagnosis, contraception, or medical advice.

PeriodPal is the period tracker built for two. You log your cycle once. The people you invite see it on their own phones the moment you save it, read only. SHARED THE INSTANT YOU LOG IT Mark a period day with its flow, add symptoms, mood, sexual activity, or a note. Whoever you have invited sees the update immediately. No screenshots, no recap texts. You log it once and the person supporting you already knows. YOU DECIDE WHO SEES IT Sharing starts with an invite link that works exactly once, for the person you sent it to. Viewers get read only access: they can see, never edit. Share with a partner, a parent, anyone you trust, and each one separately. REVOKING IS INSTANT AND TOTAL Remove a viewer in one tap and they lose everything that same moment: your history as well as anything new. No grace period, no leftover copies in their app. QUIET ON THEIR LOCK SCREEN When you log, your viewers get a notification that just says "New update". No cycle details on anyone's lock screen unless that viewer opts into more on their own device. Your notes are never included either way. HONEST ESTIMATES, NOT PROPHECY PeriodPal projects your next periods from your own cycle lengths, and marks an estimated fertile window and ovulation day for each one. Estimates from your dates and nothing else: no conception coaching, no pregnancy scoring, never a contraceptive method, and no pretending to know more than the data does. PRIVATE ON PURPOSE No analytics SDKs, no ads, no data brokers, ever. Your data is encrypted in transit and at rest, and it is shown only to you and the viewers you chose. Sign in with Apple and hide your email if you want. Deleting your account is a real delete: every log, every share, every invite, gone. RECOMMENDED FOR * Couples who are done with the "day 3, feeling rough" recap texts * Anyone who wants their partner to just know, without being asked * Parents staying quietly in the loop with a teen who wants them there * Anyone who wants period tracking without ads, analytics, or upsells Free. No ads, no subscription. Privacy policy: https://periodpal.iamyash.com/privacy/ Support: yashpatel26@gmail.com
