First, make sure you're online and relaunch the app. If Pro still shows as locked, open Settings → Pro in the app and tap Restore purchase. This re-checks your purchase with the App Store and unlocks Pro on any device signed into the same Apple Account. If that doesn't fix it, email us with the approximate purchase date and we'll get you sorted.
No. Protocol Pro is a one-time purchase — pay once, keep it forever. There are no recurring charges and nothing to cancel. Protocol+ is a separate optional subscription (monthly or annual) for live interaction checks.
To restore on a new device, open Settings → Protocol+ in the app and tap Restore purchase (use the same Apple Account). To cancel, open the iPhone Settings app, tap your name, then Subscriptions → Protocol+. Protocol+ keeps working until the end of the period you paid for. While you are subscribed it includes every Pro feature; if you also bought Protocol Pro separately, you keep Pro after Protocol+ ends.
The free tier includes up to 5 supplements with check-offs, streaks, and 7-day history. Protocol Pro removes the limit and adds the interaction detail view, barcode scanning, automatic stock tracking, refill and daily reminders, 30-day adherence, and Apple Health sync.
Everything lives on your iPhone. Protocol has no accounts, no cloud service, no analytics, and no ads — we can't see your logs, and your stack stays on your device unless you subscribe to Protocol+, which sends supplement names (no identifiers) to check them for interactions. See the Privacy Policy for the full picture.
Not yet. Your data is included in your normal iPhone backup (iCloud or computer), so restoring your phone restores Protocol's data. Deleting the app deletes its data, and we can't recover it — so don't delete the app to "reinstall fresh" unless you mean it.
Reminders are a Pro feature. Turn on notifications in Settings inside the app, then Protocol schedules local reminders on your device: daily reminders for each time slot in your stack, and a refill alert when a supplement drops below its days-remaining threshold. Nothing is sent from a server — if your phone is off at the scheduled time, iOS delivers the notification per its normal rules.
With Pro, you can turn on Write doses to Apple Health in Settings. Checked-off doses are written into Apple Health as nutrition records. It's one-way (Protocol never reads your Health data) and you can revoke access anytime in iOS Settings → Health → Data Access & Devices.
The scanner looks products up in the NIH Dietary Supplement Label Database, a free public database run by the U.S. National Institutes of Health — its coverage is strongest for products sold in the US, so UK/EU or niche brands are sometimes missing. If a product isn't found, you can add it manually or pick it from Protocol's built-in catalogue search. No camera images ever leave your phone; only the barcode number is looked up.
No. Interaction and timing notes are general educational information from published research. They aren't advice about you, and Protocol doesn't know your medications, conditions or circumstances. Some notes mention medicines or health conditions in general terms (for example, that a supplement may affect how a blood thinner works) to help you know what to ask your doctor or pharmacist about. They are not a complete list, and nothing here replaces professional advice. Always check with a doctor or pharmacist before changing what you take, especially if you take medication, have a health condition, or are pregnant or breastfeeding. See our Terms of Use.
Purchases are processed by Apple, so refunds go through Apple: visit reportaproblem.apple.com, sign in with your Apple Account, and request a refund for Protocol Pro. We're unable to issue App Store refunds ourselves.
In the app: Settings → Clear all data erases everything instantly. Deleting the app from your phone does the same.
