If you subscribed on iOS:

1. Open the Settings app on your iPhone or iPad
2. Tap your Apple ID at the top
3. Tap Subscriptions
4. Tap OnePin
5. Tap Cancel Subscription

If you subscribed on Android:

1. Open the Google Play Store app
2. Tap your profile icon > Payments and subscriptions > Subscriptions
3. Tap OnePin > Cancel subscription

If you subscribed on the web (Stripe):

1. Open OnePin in your browser
2. Go to Settings > Account > Manage Subscription
3. Click Cancel Subscription in the Stripe portal

Cancellation takes effect at the end of your current billing period. You keep premium access until then.

New users get a 30-day free trial of OnePin Premium. Your card is required at signup but is not charged until day 30. You can cancel anytime during the trial and you will not be charged.

After the trial, Premium is $49.99/year (USD). If you do not subscribe, you can keep using the Free tier with limited features (for example fewer protocols and inventory items; Premium features like cloud sync and AI stay locked).

Open OnePin and go to Settings > Data > Import/Export. You can export:

• JSON backup - complete snapshot of all your protocols, inventory, dose logs, and settings
• Protocols CSV - your protocols in spreadsheet format
• Inventory CSV - your inventory in spreadsheet format

To delete your account and all associated data:

1. Open OnePin and go to Settings > Account > Delete Account, OR
2. Email support@onepin.app from the address on your account with the subject "Delete my account"

All your data is removed within 30 days. This action is irreversible. Export your data first if you want a backup.

OnePin Premium lets you track protocols for yourself plus a partner from one app. Each "person" has their own protocols, inventory, and dose history. Switch between persons via the chip selector at the top of the Home tab.

True multi-device household sync (where each partner has their own login) is on the roadmap.

No. OnePin is a tracking and education tool only. It does not provide medical advice, diagnosis, or treatment. Compounds you track may be regulated as research chemicals or supplements depending on your jurisdiction. Always consult a qualified physician before starting, changing, or stopping any protocol.

The compound interaction database is a starting reference, not a guarantee of safety. Verify everything independently.

Email support@onepin.app with:

• What you were doing when the bug happened
• What you expected vs. what actually happened
• Screenshot or screen recording if possible
• Your device + OS version (e.g., "iPhone 15 Pro, iOS 18.2")
• The OnePin version (shown in Settings footer)

For feature requests, just describe what you want to do and why. We read every email.

Make sure you signed in with the same email address on both devices. If sync still hasn't happened after 1-2 minutes:

1. On the new device, go to Settings > Account and verify the email matches
2. Force-quit and reopen OnePin
3. If still missing, email support@onepin.app with the email address on your account
