Written from what the app actually does

Privacy Policy

Pep-Tidy is operated by JAMSTECH LLC. This page describes exactly what the site stores, why it stores it, and how to get it removed.

Last updated: August 31, 2026

You can use most of the site without an account

The dose calculator, per-peptide reconstitution calculators, peptide library, reconstitution guide and the Pep-Talk blog all work with no account and no personal details. If you never sign in, never subscribe and never send a message, we hold no information that identifies you.

Account data

Signing in creates an account through our authentication provider (Supabase Auth), including the option to sign in with Google. In that case we store your email address and the authentication identity that links your sign-in method to your account. We never receive or store your Google password.

Once signed in, anything you create is stored against your account:

  • Protocols: peptide, vial size, reconstitution volume, dose, schedule, cycle and start dates, and your low-supply preferences.
  • Dose logs: which dose you marked taken or skipped, and when.
  • Weight entries: the weight and date you enter in the weight tracker.

This data exists so the calendar, supply math and history can work. It is not used for advertising.

Analytics

We use Google Analytics 4 to see aggregate page views and traffic sources. It is enabled only when a measurement ID is configured, so it may be switched off entirely, and it never runs on admin pages. We also keep our own internal page-view counter that records the path visited, the referring page, a random session identifier, your browser's user-agent string and, if you are signed in, your account ID. We use it to understand which tools people actually use.

Affiliate link clicks

When you click an Amazon product link on Pep-Tidy, we record the product, the page you clicked it from, a session identifier, the referrer and your user-agent so we can tell which recommendations are useful.

We never see what anyone buys. Amazon does not report purchases, carts or order contents back to us at an individual level. See our affiliate disclosure for how those links work.

Newsletter

The Pep-Talk newsletter is double opt-in: we store your email address and whether you confirmed it, and you only receive mail after clicking the confirmation link. Every email contains a one-tap unsubscribe link, which removes you immediately. We do not sell or share the list.

Contact form

The contact form collects your name, email address, the topic you pick and your message. We use it to reply to you and to fix what you report. It is not added to the newsletter.

Push notifications

If — and only if — you turn on dose reminders, your browser or device creates a push subscription and we store it so reminders can be delivered. Turning reminders off, or revoking notification permission in your browser, ends that. We store no notification content beyond what is needed to send the reminder.

Local storage and cookies

Pep-Tidy keeps a small amount of data in your own browser:

  • Your 21+ and disclaimer acknowledgement, so the notice does not reappear on every visit.
  • Interface preferences such as unit choice, warning settings and dismissed walkthrough cards.
  • A session identifier used for page-view and affiliate-click counting.
  • Your authentication session, if you are signed in, so you stay signed in.

There are no advertising or cross-site tracking cookies on Pep-Tidy today. If that ever changes, this page will be updated before it does.

Your rights: deletion and export

Send a request through the contact form and we will export a copy of your data or delete it. Deleting your account removes your protocols, dose logs and weight entries. Newsletter removal is instant through the unsubscribe link in any email.

We do not sell personal information

Pep-Tidy does not sell or share personal information for money or for cross-context behavioural advertising, as those terms are used in California law, and we do not transfer your data to advertisers. Wherever you live — including under the GDPR — you can ask us to access, correct, export or erase your data through the contact form. We keep account data only for as long as the account exists.

Children

Pep-Tidy is intended for adults aged 21 and over. The site is not directed at children, and we do not knowingly collect information from anyone under 18. If you believe a child has created an account, tell us and we will remove it.

Changes and contact

Material changes to this policy will be reflected in the "last updated" date above. Questions about privacy go through the contact form, which is the only contact route for JAMSTECH LLC. See also our Terms of Service.
