Privacy Policy

1. Information we collect

Device identifier: a device fingerprint used for license activation checks. It is generated by your browser, stored locally (localStorage), and used only to validate license entitlements and device counts when you activate Pro.

Order information: order number, plan, amount, payment provider transaction ID, and any contact details you voluntarily provide when purchasing Pro.

Payment information: payments are processed by licensed providers such as Alipay and WeChat Pay. We never touch or store sensitive payment data such as card numbers or passwords.

2. Image data

All compression, conversion, resizing, and cropping runs locally in your browser via Web Workers and WebAssembly. Images are never uploaded to our servers and no server-side copies are kept.

Temporary processing data is destroyed as soon as you close the page.

3. Local storage

We use localStorage to persist your device identifier and license profile cache, which provides an offline grace period when our service is unreachable. You can clear this data at any time in your browser settings; doing so requires re-activating Pro.

4. Use and retention

Collected information is used only to: provide license activation, process orders and support, and prevent abuse such as code sharing or bypass attempts.

Order and activation records are retained no longer than legally required after you stop using the service. You may request access, correction, or deletion of your personal information via the contact details below.

5. Third-party services

Payments are handled by Alipay (Alipay (China) Network Technology Co., Ltd.) and WeChat Pay (Tenpay Payment Technology Co., Ltd.); their data handling is governed by their respective privacy policies.
