Privacy Policy
Effective date: October 29, 2026
1. Data controller
zhongke, based in China, is the data controller for personal data processed through the videocompression website at https://videocompression.org. Contact: zhongke0819@gmail.com. We have not appointed a Data Protection Officer (not applicable at our current scale).
2. What we collect
We collect only what the Service actually needs. In particular:
- Your files — never. Images and videos you compress are processed entirely in your browser. They are never uploaded to, stored on, or transmitted through our servers. We cannot see them.
- On-device preferences. Language choice and lifetime compression statistics are stored in your browser's localStorage and stay on your device. Clearing site data removes them.
- Payment information — handled by our processor. Payments are processed by Waffo Pancake, our PCI-DSS compliant merchant of record. Card numbers are entered on Waffo Pancake's secure checkout and never stored by us. We receive only order confirmations (your email, plan, transaction ID, amount).
- Support correspondence. If you email us, we keep your message and address to respond.
We do not collect: accounts or passwords (the Service currently requires no account), location data, device identifiers for advertising, or biometric data.
3. How we use your data
| Purpose | Legal basis (GDPR Art. 6) |
|---|---|
| Operating the compression tool in your browser | Performance of a contract |
| Processing payments and preventing fraud | Performance of a contract; legal obligation |
| Responding to support requests | Legitimate interest |
| Complying with tax and accounting law | Legal obligation |
4. Cookies and tracking
- Strictly necessary (cannot be disabled): localStorage entries for language preference and on-device statistics. No consent banner is needed for these because they never leave your device.
- Analytics / marketing: none. We currently use no analytics tools, no advertising pixels, and no cross-site trackers. If this changes, we will update this policy and obtain consent where required.
5. Sharing and disclosure
We do not sell your personal data. We share data only with:
- Waffo Pancake — payment processing (merchant of record, PCI-DSS). Card data goes directly to them, never through us.
- Public CDNs (jsDelivr, unpkg) — we load open-source libraries (e.g. the video encoding engine) from these networks; they may see standard request metadata such as your IP address and user agent, governed by their own privacy policies.
- Authorities — only when required by law.
6. Data security
Our architecture is our strongest safeguard: because files never leave your browser, there is no file database to breach. For the data we do handle, we use TLS-encrypted connections, least-privilege access to our systems, and the hardened practices of our infrastructure providers (Vercel). If a personal data breach occurs, we will notify the competent supervisory authority within 72 hours where required, and affected users without undue delay.
7. Retention
- Your files: never stored — retention is zero by design.
- On-device preferences/statistics: until you clear your browser's site data.
- Transaction records: retained as required by applicable tax and accounting law.
- Support correspondence: up to 24 months after the conversation ends.
8. Your data rights
Under the GDPR (and similar laws such as the CCPA), you have the rights to access, rectify, erase, restrict, port, and object to processing of your personal data, and to withdraw consent where processing is based on consent. To exercise any right, email zhongke0819@gmail.com — we respond within 30 calendar days. You also have the right to lodge a complaint with your local data protection authority.
9. Marketing and opt-out
We do not send marketing emails — there is no newsletter and no advertising use of your data. Transactional and security notices (payment receipts, security alerts) are not marketing and cannot be opted out of while you hold a paid plan.
10. International transfers
Payment processing via Waffo Pancake may involve transfers outside your country. Where personal data leaves the EEA/UK, we rely on appropriate safeguards such as the EU Standard Contractual Clauses.
11. Children's privacy
The Service is not directed at children under 16, and we do not knowingly collect personal data from anyone under 16. If you believe a child has provided us personal data, contact zhongke0819@gmail.com and we will delete it.
12. Third-party links and services
The site may link to third-party sites or load third-party libraries (see Section 5). We are not responsible for their content or privacy practices; their policies apply when you use them.
13. Changes to this policy
We may update this policy from time to time. Material changes will be announced on the website at least 15 days before taking effect. The effective date at the top always shows the current version.
14. Contact us
For privacy questions, data-rights requests, or complaints: zhongke0819@gmail.com. We aim to respond within 2 business days.
