Privacy Policy

Last updated: November 11, 2026

ramda lab (https://lab.ramda.io/, "the site") is a small collection of tools that run in your browser, operated by an individual. This page covers the whole site. The Chrome extensions each have their own privacy policy.

1. Files (images, PDFs, etc.)

• Compressing, converting and resizing images, merging and splitting PDFs, and making QR codes all happen inside your browser. The files you pick are not uploaded to any server.
• The operator does not receive or store file contents, file names or results.
• Some tools (for example image upscaling) download a trained model file from this site. That is a download to your browser; none of your files are sent.

2. Analytics

• To count visits, the site uses Cloudflare Web Analytics from Cloudflare, Inc. It sets no Cookies, does not track you across devices, and does not collect personally identifying information.
• The statistics include page URL, referrer, browser type, country and page-load timing.
• See Cloudflare Web Analytics and the Cloudflare Privacy Policy.
• For visits from Google Search, the operator sees search queries and impression counts in Google Search Console. These are aggregates provided to the operator; individual visitors are not identified.

3. Cookies and browser storage

The site currently sets no Cookies and stores nothing in browser storage such as localStorage.

4. Advertising

The site currently shows no ads.

5. Paid version and payments

A one-time office edition (¥2,980) is on sale. Payment is handled on a payment page provided by Stripe, Inc.; the operator never receives card numbers. The purchase completion page sends the checkout ID (session_id) in its URL to this site's server, which asks Stripe whether it was paid and then issues a license key. The key is stored in your browser's local storage (localStorage), and the tools ask this site's server whether it is valid when opened. File contents are never sent. The operator receives only what is needed to confirm a purchase (email address, date and time, amount, payment ID) and uses it only for billing, support and legal record-keeping. Sales terms will be published on the "Specified Commercial Transactions Act" page.

6. Sharing of personal information

Except where required by law, user information is not shared with third parties. The site currently collects no personal information (other than what you send when you contact the operator).

7. Contact

Email addresses and messages you send are used only to reply and respond, and are deleted after the necessary period. Contact: [email protected]

8. Changes

When this policy changes, this page and the "Last updated" date will be updated. It will be updated before ads or a paid version start.
