Privacy policy

Last updated 31 October 2026

This policy covers the website tuper.app. Each Tuper product (ReplaceKit, Indexkeeper, Formwell, Dutyroll, Stockcount) has its own privacy policy on its own site, which describes the data that product handles; where the two differ, the product's policy applies to that product. Contact: support@tuper.app.

This website

tuper.app uses no cookies, no analytics and no third-party scripts, and it has no forms. Our web server processes the technical data any web request carries (such as the page requested and the browser type) only to deliver the page; we do not build profiles from it.

When you email us

If you write to support@tuper.app or another tuper.app address, we keep your email address and message to answer you and to handle your account, billing or refund. We do not add you to a mailing list because you wrote to us.

Waitlists

If you join a product waitlist, we store your email address, the time and the product or plan you chose, and use them only to email you about that product. Every email lets you opt out; write to us and we delete the address.

Payments

Purchases are processed by Polar (polar.sh), our merchant of record, under its own privacy policy. We receive your name, email address, country, what you bought and the subscription status, never your full card number. Apps billed through a platform marketplace (such as Shopify) are covered by that platform's policies as well.

What we never do

We do not sell or rent personal data, do not use it for advertising, and do not use customer content to train AI models.

Your rights

You can ask us for a copy of the personal data we hold about you, to correct it, or to delete it, by writing to support@tuper.app. We reply within 30 days. If you are in the EU or UK, you can also complain to your data protection authority.

Changes

If this policy changes we update the date above.
