Why this page isn't a typical cookie policy
Most "cookie policies" exist because sites set dozens of third-party cookies for ads, retargeting, and cross-site tracking. Bluebird does none of that. We don't have an ad network, we don't have a marketing pixel, and we don't have a user account system that needs a session cookie. So instead of a generic template, here is a plain, item-by-item list of what actually gets written to your browser.
What we save to localStorage
Everything in this list is stored using the browser's native window.localStorage API. It lives on your device only. It is never uploaded, never synced across devices, and never readable by other websites.
- Theme choice — whether you picked light or dark mode.
- Favorite tools — the tools you starred so they appear at the top of the home page.
- Recent tools — the last few tools you opened, so you can jump back to them.
- Per-tool settings — for example, the quality slider on the image compressor remembers your last value so you don't have to set it again.
- Cookie/disclosure banner state — a single flag so we don't show the banner again after you dismiss it.
That's the complete list. Nothing here identifies you, and nothing here is transmitted off your device.
What we do NOT use
- Google Analytics, Google Ads, or DoubleClick cookies
- Facebook Pixel or any social-media tracker
- Third-party advertising cookies of any kind
- Session-replay tools that record your interactions
- Cross-site tracking, fingerprinting, or device graphs
- Server-side session cookies (there is no login)
Light, first-party analytics
Our hosting provider records aggregated page-view counts so we know which tools people find useful. This is first-party, cookie-light, and does not follow you across other websites. We honor your browser's Do Not Track signal.
Clearing what we saved
You can wipe everything Bluebird stored by clearing site data for this domain in your browser settings. Doing so resets your theme, favorites, recents, and per-tool preferences. It will not affect any tool's functionality — every tool works on a fresh visit with no stored state.
Files you open in a tool
Files you drag into a Bluebird tool are held in temporary browser memory (and, for very large files, in a private on-device sandbox called the Origin Private File System) only for as long as the tab is open. They are not written to localStorage, not uploaded, and are discarded when you close the tab.
Changes to this disclosure
If we ever add a new category of on-device storage, we will update this page and re-show the disclosure banner so you can review it.
