Privacy Policy

Last updated: 19 May 2026

1. Who we are

MiniPx (minipx.com) is operated by Gaurav Bhowmick, an individual sole proprietor based in India. For any privacy question, write to contact@minipx.com.

2. Your image files

This is the most important thing in the document. Your image files never leave your browser. When you drop an image into MiniPx, it is read, processed, and re-encoded entirely by JavaScript running on your device. The compressed output appears in your browser memory and is downloaded directly to your computer. At no point is the image data transmitted to our servers, to Netlify, to Google, to Paddle, or to anyone else.

You can verify this yourself: open browser DevTools, switch to the Network tab, drop in an image, watch the compression run. No image data is transmitted. The source code for the compression engine is published on GitHub for further inspection.

3. What we do collect: anonymous analytics

We use Google Analytics 4 (property ID G-CPKR150KT7) to understand traffic patterns and feature usage. The data sent to Google is anonymous and aggregated. It includes:

• Page views and time on page.
• Approximate location at country and city level (derived from IP, which Google anonymizes before logging).
• Browser type, device type, operating system.
• Referring URL (where you came from).
• Compression-related event metadata: file extension, input and output sizes in KB, compression ratio, format chosen, mode used. We do not send filenames or file contents.

We use this data to understand which tools are popular, which need work, and where users get stuck. We never tie this data to a person or attempt to re-identify visitors. Google's own privacy policy and your control over Google's tracking apply: see policies.google.com/privacy and Google's opt-out browser add-on.

4. What we do collect: payments (Pro only)

If you purchase MiniPx Pro, the payment is processed by Paddle.com Market Ltd. Paddle is the merchant of record. They collect what is necessary to complete the transaction and handle tax compliance:

• Your name and billing email.
• Your billing country (for VAT, GST, or sales tax).
• Card details (which Paddle never shares with us).
• Your purchase amount and the product purchased.

Paddle stores this data under their own privacy policy: paddle.com/legal/privacy. From Paddle we receive only a webhook notification that the purchase occurred, with your customer ID hashed before we log it. We do not store your name, email, or card information on our servers.

Your Pro license itself (the Paddle transaction or subscription ID) is stored in your browser's localStorage on the device where you activated it. You can clear it at any time from the account page.

5. Cookies and local storage

We use a small number of cookies and localStorage items:

• Google Analytics cookies (_ga, _gid, _ga_…) for traffic analysis. These are first-party cookies set by your browser.
• localStorage key "minipx_pro_license" containing your Pro license (transaction/subscription ID, plan, expiry, last validation timestamp). Only set if you purchase Pro.
• localStorage key "minipx_saved_presets" containing your saved tool settings, once you start using saved presets (Pro feature). Plain JSON, sits only on your device.

No advertising cookies. No cross-site tracking pixels. No session replay tools.

6. Server logs

The site is hosted on Netlify. Netlify keeps standard server logs of HTTP requests (IP address, user agent, requested path, response code, timestamp) for security and abuse prevention. These logs are not sold or shared and are rotated regularly. See netlify.com/privacy for their data handling.

7. Your rights under GDPR and the India DPDP Act

You have the right to:

• Know what data we hold about you (in practice: very little, see above).
• Request a copy of your data.
• Ask us to correct or delete your data.
• Withdraw any consent for analytics (we will respect Global Privacy Control / Do Not Track signals where supported).
• Lodge a complaint with your local data protection authority.

To exercise any of these rights, email contact@minipx.com. For Pro purchases, you can also exercise these rights through Paddle directly.

8. International transfers

Google Analytics processes data in the United States. Paddle processes payment data in the United Kingdom, the United States, and the European Union. Netlify hosts the site from a global CDN. All three are covered by standard contractual clauses or equivalent transfer mechanisms.

9. Children

MiniPx is a general-purpose utility, not a service targeted at children. We do not knowingly collect data from anyone under 13 (or under 16 in the EU). If you believe a child has provided us with data, write to contact@minipx.com and we will delete it.

10. Changes to this policy

We update this policy when our practices change. When we do, we update the "Last updated" date at the top. For material changes, we will surface a site-wide notice for two weeks.

11. Contact

For any privacy question, write to contact@minipx.com. We aim to respond within 7 days.
