We do not ask you to create an account, and we do not run advertising trackers on this site.
When you buy something, our payment provider (Creem, acting as merchant of record) collects the information needed to process the payment and calculate tax — typically your name, email address, country and payment details. We receive your email address and order details so we can deliver your files and provide support. We never see or store your full card number.
If you email us, we keep that correspondence so we can help you.
To deliver files, provide support, handle refunds, and meet tax and accounting obligations.
We do not sell your personal information, and we do not send marketing email unless you ask us to.
This site does not set advertising cookies. Our free calculators run entirely in your browser — the numbers you type are never sent to our servers. Clearing your browser data removes anything stored locally.
We share data only with the service providers needed to run the shop: our payment provider (Creem), our email delivery service, and our hosting provider (Cloudflare).
You can ask for a copy of the personal data we hold, ask us to correct it, or ask us to delete it — email zhenchigaofei1@gmail.com. If you are in the EU/UK you also have the right to complain to your local data protection authority.
