Short version: your mail files never leave your computer. We do not use analytics, advertising or cookies.
Your mail files
When you open a file, your browser reads it locally and Letterlark processes it in the page. The app page is protected by a Content Security Policy with connect-src 'none', which makes the browser block any network request from the app, including from its background worker. Remote images and links in emails are not loaded. You can verify this in your browser’s developer tools.
Data stored on your device
Your language choice and, if you enter one, your license key are saved in your browser’s local storage. The app files are cached so it works offline. You can remove all of this by clearing the site data in your browser.
The website
The pages are static files without tracking scripts, analytics or cookies. The hosting provider that delivers the pages may record standard technical request logs (such as IP address and time) as part of operating the service.
When you order
Your order is an email you send yourself, containing your name (optional), email address and order details. We use it only to check the payment and send your license key, and we keep a record of issued licenses. USDT payments are public on the TRON blockchain by nature; PayPal payments are processed by PayPal under its own privacy policy.
