Privacy Policy
legal.updated: 2026-09-13
Plain-language summary: this site runs first-party, cookie-free analytics, your account holds only a username, an email address and a password hash, and the browser tools process your data locally. Nothing is sold.
What we collect
Anonymous usage statistics: a random 128-bit identifier stored in your browser under the key sac_uid, plus the pages you view, time spent, scroll depth, the referring URL when you arrive, and coarse device and country information derived from the request. The identifier carries no personal data and is not linked to any account. If you create an account we also store the username and email address you choose, and a salted password hash — never the password itself.
Cookies
We set no cookies. Analytics uses the sac_uid value in localStorage, not a cookie, and sessions are derived on the server from a 30-minute inactivity window. That is why you are not asked to accept a tracking banner today.
Browser tools never upload
The JSON formatter, Base64, hashing, timestamp, QR and image tools run entirely in your browser. The text, tokens and images you paste or open are not transmitted to us or to anyone else. The image editor in particular keeps every pixel on your device, including when it strips EXIF metadata.
Opting out and deleting your data
Analytics respects the Do Not Track header, and you can opt out at any time by setting localStorage key sac_no_track to 1 in your browser console, or by clearing site data for this domain. To delete an account and its data, email us and we will remove it; analytics rows are pruned automatically, and by default raw visit records older than 365 days are deleted while anonymous aggregate counts are kept.
Third parties
Cloudflare sits in front of this site as a content delivery network and security layer, so it processes request metadata such as IP address and user agent on our behalf. There are no advertising networks, no social trackers and no data brokers on this site. If we ever introduce advertising or third-party analytics that rely on cookies, we will update this page and ask for your consent before anything is set.
Contact
Questions, corrections or deletion requests: [email protected]. If your request concerns a piece of content, [email protected] reaches the editorial mailbox. This policy describes current practice on this site only.
