Sync Period

Support

Help with private, local-first cycle tracking.

Start with these checks

For notifications, confirm permission in iOS Settings. For partner access, ask the tracker for a fresh complete private invite. For restore problems, confirm the backup is unedited JSON exported by Sync Period.

Protect health information

Never send a backup, partner invite, access locator, recipient key, PIN, health information, or an unredacted screenshot through a public issue. Use the private support email below for privacy, deletion, security, and app-support requests.

Data and partner sharing

You can change partner permissions, stop sharing, export a private backup, restore a backup, or permanently delete local data from the in-app Privacy Center. Stop partner sharing before deleting local data to remove the current encrypted relay update immediately.

Medical questions

Sync Period provides estimates and pattern summaries, not diagnosis, contraception, or medical advice. Sync support cannot provide medical advice or emergency care. Contact a qualified clinician or local emergency service for urgent health concerns.

Private contact

Sync Period is operated by Wei Jian Wong. Email wayne@giraffeguru.com. Please describe the issue without attaching health data, backups, private invitations, keys, or sensitive screenshots unless support specifically requests a safe transfer method.

See the Sync Period Privacy Policy.
