Privacy Policy

Data processing

blackdroid.dev is mostly a collection of client-side tools: text you paste into them is processed locally in your browser and is not sent to our servers.

A few features do send data to our server:

• AI tools — the text you enter is relayed to an AI model provider to generate a response.
• URL-fetching tools (robots.txt, sitemap and OpenAPI validators, the CORS tester server probe) — the URL you enter is fetched by our server so it can be analyzed.
• Hosted apps (Mail Blackhole mailboxes, Watchdroid uptime monitors) — these store your configuration and the received messages or check results in your account after sign-in.

Accounts & sign-in

Some features require sign-in via Google or GitHub OAuth. When you sign in, the provider shares basic profile data (name, email address, avatar) which we store to identify your account. A session cookie keeps you signed in; it is removed when you sign out. No password is ever collected or stored by us. Tools that run in your browser still process your input locally, whether you are signed in or not.

Cookies

We use the following categories of cookies and browser storage:

• Strictly necessary — session and security (CSRF) cookies required for sign-in and the site to function. These cannot be disabled.
• Preferences — localStorage entries (prefixed bd-) that remember settings such as your theme and tool inputs.
• Advertising — Google AdSense cookies, only set if you accept them in the consent message.

Advertising consent is managed by Google's certified consent management platform (CMP). You can review or change your choices at any time: Cookie settings

Advertising

We use Google AdSense to display ads. Visitors in the EEA, the UK and Switzerland are shown a consent message; if you accept, Google and its partners may use cookies and similar technologies to serve personalized ads based on your prior visits to this and other websites. If you decline, you may still see limited, non-personalized ads that do not use cookies.

• Google's use of advertising cookies enables it and its partners to serve ads based on your visits.
• You may opt out of personalized advertising at Google Ads Settings.
• For more information see How Google uses information from sites that use its services.

Analytics & logs

Our hosting provider may keep standard server logs (IP address, browser, timestamp) for operational and security purposes.
