Legal

Terms of use

The rules for using Peptiday, in plain words.

Last updated November 12, 2026

The license

Peptiday is licensed to you under Apple's Standard Licensed Application End User License Agreement, together with these terms. If they conflict, Apple's agreement wins. By using the app or this website, you agree to both.

Not medical advice

Peptiday is a tracker and an educational reference. It doesn't diagnose, treat or prevent any condition, and it never suggests what to take, how much, or when. Decisions about medicines and peptides belong to you and a qualified clinician. Talk to one before starting, stopping or changing treatment. In an emergency, call your local emergency number.

Many compounds in the library are not approved medicines, and their legal status differs by country. Peptiday doesn't sell, supply or recommend any compound or seller.

Estimates and the library

Estimated levels are drawn from published half-lives and an assumed absorption rate. They are population estimates, not measurements of your body. Before-and-after comparisons show what changed in your data, not why it changed. Both can be wrong.

Library entries and lessons are editorial summaries of the cited sources and have not been clinically reviewed. They can contain errors or fall out of date. Check the sources, and email us if you find a mistake.

Who can use Peptiday

You must be 18 or older to use Peptiday.

Peptiday Pro

  • Pro is sold through the App Store as a monthly or yearly subscription, or as a one-time lifetime purchase. Apple bills you and handles payment.
  • Subscriptions renew automatically unless you cancel at least 24 hours before the end of the current period. Cancel in your App Store subscription settings. Deleting the app doesn't cancel a subscription.
  • If a free trial is offered and you don't cancel before it ends, the subscription starts and you are charged.
  • Refunds are handled by Apple under its policies. Request one at reportaproblem.apple.com.
  • Lifetime access unlocks Pro for as long as Peptiday is offered on the App Store, on devices signed in to the same Apple Account.
  • Peptiday needs an active plan or lifetime access. If a subscription ends, your records stay on your iPhone, you can still read and export your history, and reminders you already scheduled stay on while notifications are allowed, so you can log or skip a dose from one. Logging in the app, comparisons and adding compounds wait until you choose a plan again. Settings stays available, including Pause all protocols.

Your records

Your records belong to you and stay on your iPhone, as described in the privacy policy. We don't keep a copy, so we can't restore records ourselves. iCloud Backup or a direct transfer to a new iPhone carries them over, so keep device backups turned on. A CSV export gives you a readable copy of your doses, but the app can't restore from it.

Fair use

Don't misuse the app or website, reverse engineer them beyond what the law allows, or copy the library to republish it as your own. The Peptiday name and the app's design and text belong to Vlad Arama.

No warranty

Peptiday is provided “as is”. To the extent the law allows, we make no warranty that it will be accurate, available or error-free, and we aren't liable for decisions made using it or for indirect or consequential losses. Nothing in these terms limits rights you have under consumer law that can't be waived.

Changes and contact

We may update these terms. If we do, we'll change the date at the top. Questions go to vladarama2002@gmail.com or the support page.
