Privacy Policy

The short version

• The free calculator runs on your device. The numbers you type are not sent to us or stored on our servers.
• The Preptide app keeps your logs, doses, and measurements on your phone.
• If you join the launch list, we use your email only to tell you when the app is live and to share product updates. We never sell or rent it.

Information you enter in the calculator

The free calculator on this site works entirely in your browser. The vial size, bacteriostatic water, and dose you enter are used to do the math on your device and are not transmitted to or saved by us.

The launch list

If you give us your email address to be notified at launch, we store it for one purpose: to email you when Preptide is available and to occasionally share product news. You can unsubscribe or ask us to delete your address at any time by emailing [email protected]. We do not sell, rent, or trade your email.

Data in the Preptide app

Information you record in the app, such as compounds, vials, dose logs, injection sites, weight, and measurements, is stored on your device. If you choose to connect Apple Health, the app reads and writes only the data you grant permission for, on your device. We do not collect this health information on our servers.

Analytics

We may use privacy-respecting analytics to understand aggregate, anonymous usage of the website, such as which pages are visited and general device or region information. This is used to improve the site. We do not use it to build advertising profiles or identify individuals.

What we do not do

• We do not sell, rent, or trade your personal information.
• We do not run third-party advertising trackers.
• We do not collect the health data you enter in the app onto our servers.

Service providers

We rely on a small number of infrastructure providers to run Preptide, such as our hosting provider and, for the app, the Apple App Store. These providers process data only as needed to deliver the service and are bound by their own privacy terms.

Security

We take reasonable measures to protect the limited information we hold. No method of transmission or storage is perfectly secure, so we cannot guarantee absolute security.

Children

Preptide is intended for adults. It is not directed to anyone under 18, and we do not knowingly collect information from children.

Your choices

You can ask us to access or delete the email address we hold for you at any time. Because the calculator and the app keep their data on your device, you control that information directly by clearing it in your browser or app.

Changes to this policy

If we update this policy, we will revise the date at the top. Continued use of Preptide after a change means you accept the updated policy.
