Sample data
Privacy
No account. No sign-in. Nothing for us to attach a log to.
PepCore stores your protocols, doses and logs in the app on your iPhone, encrypted by iOS when your iPhone has a passcode, with an optional Face ID lock. There is no sign-in, so we hold no account for you.
Moving to a new iPhone is a backup file you AirDrop across, and that file never passes through a server of ours. Exporting your data doesn't need a subscription — your log is never held hostage.
The AI Coach was removed in version 1.0.12 and its service ended on 4 November 2026. The privacy policy sets out how it worked and what happens to data sent before then.
The app has no analytics and no third-party SDKs. Its current privacy label is on its App Store page.

Prices shown are for the App Store in the US, and the 7-day trial is for new subscribers. The App Store shows your local price, and whether you qualify for the trial, before you confirm. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless it's cancelled at least 24 hours before the end of the current period; your account is charged for renewal within the 24 hours before the end of that period. Any unused portion of a trial is forfeited when you buy a subscription. Manage or cancel yours in Settings → your name → Subscriptions. See our Privacy Policy and Terms of Use.
Questions
Common questions
What does PepCore do?
It's a personal log for a protocol you already run. You enter your own compounds, amounts and schedule; PepCore reminds you when an entry is due, shows which injection site you used last, and keeps a calendar of everything you've logged. It does not work out, suggest or check any amount.
What does the iPhone app cost?
PepCore for iPhone is a subscription app: $39.99 a year or $6.99 a month on the App Store in the US, each with a 7-day trial for new subscribers. One subscription unlocks everything: protocols, dose reminders, the injection-site map, the calendar and history, on and off schedules, the journal, blood work and body-metric logs, and backup. There is no ad-supported version and we do not sell your data.
What happens when the trial ends?
If you don't cancel, it converts to a paid subscription automatically and Apple charges the payment method on your Apple Account. If you cancel any time before the last 24 hours of the trial, you're not charged. Cancelling is in Settings → your name → Subscriptions, and it takes about four taps. Cancelling does not delete what you have logged.
Is my data sent anywhere?
PepCore stores your protocols, doses and logs in the app on your iPhone, encrypted by iOS when your iPhone has a passcode, with an optional Face ID lock. The app does not upload them to us, and we cannot see them. A backup of your iPhone that you make with iCloud or a computer can include them, under Apple's terms. There is no account, and the app has no analytics and no tracking. The AI Coach was removed in version 1.0.12 and its service ended on 4 November 2026, so older versions can no longer send anything on to the AI provider. Our privacy policy sets that out in full.
Is there an Android version?
Not yet — PepCore is iPhone-only for now.
Does PepCore give dosing advice?
No, and it never will. It's a log. It doesn't work out, recommend or check compounds, amounts, schedules or combinations. Those are decisions for you and a qualified healthcare professional.
