Privacy Policy

Effective date: 10 October 2026.

Information we collect

Google sign-in provides your name and email address. This site does not collect a profile photo. For Pro, this site stores subscription status and the Creem customer id. Creem processes the card payment and payment history. This site does not receive or store the card number. If you save a calculation, the calculator inputs are stored with your account. SKU purchase costs in the ledger are stored with your account. A CSV used for bulk calculation, and a sales report opened in the ledger, stay in your browser and are not uploaded. A normal page request can include your IP address, the time, browser type, page address, and browser language.

How information is used

The information is used to run the calculator, keep saved calculations, and check whether Pro is active. This site does not send marketing email. Creem may send its own receipt or billing message.

Security and sharing

The public site is served over HTTPS. Subscription status and saved calculations are stored on the server that hosts this site. This site does not sell, rent, or publicly disclose your name, email, or saved calculations. Creem receives the name and email needed to complete checkout. Information may be disclosed when the law requires it. No separate security certification is claimed.

Cookies

A cookie named eml_session keeps you signed in for about 30 days. A short-lived cookie named eml_oauth is used only to finish Google sign-in. If you choose a language, a cookie named locale stores that choice for about one year. This site does not use analytics or advertising cookies, and it does not use browser local storage for calculator preferences.

Your choices

You can ask to review or delete the account record and saved calculations by emailing szxhg123@gmail.com.
