Privacy Policy

Last updated: 12 November 2026

The short version

Snowtop collects as little as possible: what's needed to sell you a license and check that it's valid. No ads, no tracking, no selling of data.

What the app does

• To place snow on your windows, Snowtop reads the positions and sizes of open windows on your computer. It never reads what is inside them, and this information never leaves your computer.
• When you activate a license, the app sends your license key, a one-way hash of your computer's ID (not the ID itself) and your computer's name to our license server. About once a week it checks that the key is still valid.
• Your settings are stored only on your computer.

When you buy

Payments are handled by Paddle.com, our Merchant of Record. Paddle processes your payment details under its own privacy policy; we never see your card. Paddle shares your email address and an order ID with us so we can create your license key and email it to you.

Where data is stored

License keys, purchase emails and device hashes are stored in our database hosted by Supabase in the European Union (Frankfurt). License emails are sent through Resend. The website is hosted by Vercel.

How long we keep it

We keep license records for as long as your license exists, so we can help you if you lose your key. Ask us and we'll delete your data (your key will stop working).

Your rights

You can ask to see, correct or delete your data at any time: .
