Privacy policy

This is the privacy policy for DevKit Lab("we", "our", or "the site"), accessible at https://devkitlab.dev. This page explains what information is collected, what is not, and what you can do about it.

The short version

The tools themselves do not collect your data. Every calculation, conversion, and decode happens inside your browser — the text, tokens, passwords, or files you enter are never transmitted to us or anyone else. The site does use standard web analytics and display advertising, which collect limited, non-tool usage data as described below.

What the tools do with your input

Nothing leaves your browser. Formatting JSON, decoding Base64, testing regex, generating UUIDs, decoding JWTs, and every other tool function is implemented using JavaScript that executes on your own device. No network request carries your inputs anywhere. You can verify this by opening your browser's DevTools Network tab while using any tool — zero requests fire during tool use.

A practical consequence of this design: we could not look at your data even if compelled to. It is not stored, logged, or retained anywhere we control because it was never sent to us in the first place.

What the site does collect

Like most websites, we collect limited information to understand how the site is used and to keep it running:

• Analytics: We may use a privacy-respecting analytics provider to count page views, measure load times, and understand which tools are most popular. This data is aggregated and does not include your tool inputs. No personally identifiable information is stored.
• Server logs: Standard web server logs (IP address, user agent, page requested, timestamp) are retained for a short period for debugging and abuse prevention.
• Advertising:If display ads are shown on the site (e.g. via Google AdSense), the ad network may set cookies and collect usage data across websites to personalise ads. See the "Advertising" section below.

Cookies

The site itself does not set tracking cookies. Third-party services (analytics and advertising) may set their own cookies. You can block cookies entirely in your browser settings — the tools will continue to work without them.

Advertising

To keep the site free, we display advertising from third-party ad networks, which may include Google AdSense. These networks use cookies and similar technologies to serve ads based on your interests. This data is collected by the ad networks, not by us.

You can opt out of personalised advertising in several ways:

• Google AdSense: visit adssettings.google.com to manage your ad preferences.
• Industry opt-out portals: aboutads.info (US) or youronlinechoices.com (EU).
• Use your browser's built-in tracking protection or install a content blocker. The tools will continue to work.

Your rights under GDPR and similar laws

If you are in a region covered by the GDPR, UK GDPR, CCPA, or similar privacy legislation, you have rights over any personal data we do hold. Because the tools collect nothing and we do not maintain user accounts, in practice the only data we might hold is anonymised analytics and server logs, neither of which typically identifies individuals. If you want to know what, if anything, we hold about you, contact us.

Children

The site is not directed at children under 13. We do not knowingly collect personal information from children.

Changes to this policy

If this policy changes, the revised version will be posted here with an updated "last updated" date. Substantial changes will be highlighted on the homepage.
