Cookie Policy
Last updated: 4 October 2026
ConvertHubcom uses a short list of its own cookies and browser storage, and no advertising or cross-site tracking cookies. Everything below is set by our own site. This page lists exactly what's stored and why. See also our Privacy Policy.
| Name / purpose | Type | Duration | Optional? |
|---|---|---|---|
| theme Remembers your light, dark or system choice | localStorage | Until you clear site data | No, it keeps the setting you chose |
| sb-<project>-auth-token (may be split into .0, .1) Keeps you signed in | Cookie (ours; readable by the page's scripts) | Up to 400 days, or until you sign out | No, only set if you sign in |
| sb-<project>-auth-token-code-verifier A one-time check that completes sign-in securely | Cookie (ours) | Removed when sign-in finishes | No, only set while you sign in |
| ch_auth_next Remembers which page to return you to after sign-in | Cookie (ours, sent only to /auth/callback) | 15 minutes | No, only set while you sign in |
| cookie-consent Remembers that you've closed the cookie notice | localStorage | Until you clear site data | No, needed so we don't show the notice again |
| converthub:recent-tools The “Recent” row on the tools page | localStorage | Until you clear site data | Stays on this device. Clear this site's data to remove it (the Preferences switch isn't working yet) |
| chub:default-processing-mode Your “Default processing” choice in Preferences | localStorage | Until you clear site data | Yes, only set if you change it |
| convert-hub-signatures Signatures you save in Fill & Sign | IndexedDB | Until you delete them or clear site data | Yes, only if you save a signature |
| keyval-store The OCR language data PDF to Word downloads, kept so it isn't downloaded again (no personal data) | IndexedDB | Until you clear site data | Yes, only if you use OCR |
| Vercel Web Analytics (page views) Counts page views on every visit, without cookies or browser storage (see Privacy Policy, section 6) | Nothing stored on your device | Not applicable | Not optional on this site, but nothing is stored, and a content blocker stops it |
The files you open in our tools aren't stored in cookies or sent to us, and saved signatures stay in this browser (convert-hub-signatures above). The one exception is Save for later in Fill & Sign, for signed-in accounts, which uploads the draft you choose to save (see the Privacy Policy, section 1).
