Privacy Policy

Last updated: November 4, 2026

The short version

Your images never leave your device. Batchmarkr watermarks images inside your web browser using Web Workers. Images are never uploaded to our servers, so we cannot see, store, analyse or share them.

What we store

• Account data: your email address and a salted, one-way hash of your password (scrypt). We never store your password itself.
• Session data: a hashed session identifier so you stay signed in (an essential, first-party cookie).
• Usage counters: the time and number of images you watermarked, used to enforce the free plan's hourly limit and to show you monthly statistics. We do not record file names, sizes, contents or any other information about your images. Per-image timestamps are deleted after about an hour.
• Subscription data: if you subscribe, your Stripe customer and subscription identifiers and the subscription status.

What stays in your browser

Your watermark design, logos, uploaded fonts and presets are saved in your browser's local storage (localStorage and IndexedDB) on your device only, so they're there next time. Clearing your browser data removes them.

Payments

Payments are processed by Stripe. Card details are entered on Stripe's pages and never touch our servers.

Advertising

For visitors and free accounts we may show ads served by Google AdSense. Google may use cookies to serve and measure ads, as described in Google's advertising policies. Where required by law (for example in the EEA and UK) you will be asked for consent first. Premium pages load no advertising or other third-party code at all.

Emails

We only email you when you ask for it, for example to reset your password.

Your rights

You can change your password or permanently delete your account and associated data at any time from your account page. For any other request, contact us at support@example.com.

Changes

If we change this policy we will update this page and the date above.
