Privacy policy

Last updated 31 October 2026

This policy explains what information MarginSlip collects and how it is used. The product is provided by Sehari Sejuta Enterprise (SSEGLOBALMARKET), Malaysia ("we").

What we collect

When you buy: your name, email address, country and order details. Lemon Squeezy, our merchant of record, processes the payment. We never see your full card details.
When you sign in: your license key and the number of devices it is activated on.

What stays on your device

The prices, costs and saved calculations you enter are stored in your own browser. They are not sent to us. Clearing your browser data deletes them, so export a CSV if you want a copy.

Third parties

Lemon Squeezy: checkout, payment, tax, receipts and license keys (their privacy policy).
Frankfurter (European Central Bank data): when you update exchange rates, your browser requests the latest rates. No personal information is sent.
Google Fonts: fonts are loaded from Google's servers.

How we use your information

To deliver your license, give support, process refunds and tell you about important product changes. We do not sell your information. We send marketing emails only if you agree to them, and every email has an unsubscribe link.

How long we keep it

We keep order records as long as required for accounting and tax purposes, and license records while your license is active.

Your rights

You can ask us to see, correct or delete your personal information by emailing seharisejutaenterprise@gmail.com. We reply within 30 days.
