ONE Privacy Policy

Effective 3 October 2026 · updated 23 October 2026

ONE is a browser extension that helps creators publish posts, stories and messages and follow notifications on their own accounts on creator platforms. This policy explains exactly what data ONE handles and why. Contact: 1onedeveloper1@gmail.com.

What stays in your browser

Your drafts, settings, post history, inbox, reminders and OneCash earnings records are stored only in your browser's extension storage. Photos and videos you publish go directly from your browser to the platform you chose; they never pass through our servers. ONE works through your own logged-in sessions on the platforms, inside your browser. Your passwords, cookies and session tokens are never sent to us.

What our servers receive

• Access check. To check your access, ONE sends us the IDs and usernames of your creator accounts that are open in your browser (LoyalFans identifies you; other platforms are shown to the administrator only so they can recognise you), a random device ID, the browser and system name (for example "Chrome · Windows", without versions), the extension version and the time of the check. If you work with a chatter, a new browser signing in to your account waits until you confirm it in your ONE. Any other new browser works right away, but managing your chatters, translating and connecting OneBOX or OneChat on other devices start working there only after you confirm it from a browser you already use; we store whether each browser is confirmed. We store a hash of the device token, never the token itself.

• Licence agreement acceptance. When you accept the ONE Licence Agreement, we record which version you accepted, a fingerprint (SHA-256) of its text, the moment of acceptance, the interface language, the extension version, the browser and system name, your device ID and your country as reported by our hosting provider (not your IP address). This is kept as proof that the agreement was concluded.

• Error reports. When publishing fails, ONE sends the platform, the tool, the kind of error, a short error description and the extension version. Reports never include your post texts, files or messages.

• OneBOX on another device (optional, only if you turn it on). Your inbox summary is encrypted on your computer with a key that exists only in your private link. Our server stores and forwards only the encrypted data and cannot read it. If you enable notifications, short notification texts are sent to your device through Apple or Google push services, encrypted end-to-end (RFC 8291). The data is erased when you turn the feature off or after 30 days without your computer connecting.

• Chatters (optional, only if you invite a chatter). We store that you have a chatter seat, when the chatter connected and when they started or ended a shift, and what you allowed them: which ONE tools, which platforms (by name, for example "f2f") and the price limits for their mass messages — the chatter's ONE needs this to know what to show. The chatter's earnings report (payments on the platforms you gave them, with fan names and amounts) and the log of their actions in ONE are encrypted with a key that exists only in the invite link; our server stores only the encrypted data and cannot read it. An invite link works only after the person confirms “Join the team” in their ONE. Revoking the chatter erases their report and access.

• OneChat (optional, live streams on LoyalFans, F2F, ScatBook, DarkFans, BestFans, ManyVids and FanSeven). While you stream — also on several of these sites at once — the chat messages and the list of viewers that your browser already sees are relayed through our server to your other devices (for example the OneChat app on your phone), and replies you send from those devices go back to your stream. If you turn on translation there, the lines are translated with OneLang as described below. Up to the last 100 events are kept only for the duration of the stream and are erased when it ends.

• OneLang translation (optional, only when you translate). When you translate chat messages or your own text, those lines (which may include messages from your fans) are sent to our server and passed to OpenAI for translation; if OpenAI is unavailable, to Google Translate. Our server does not keep the texts: it stores only how many characters and requests you translated per day, for accounting. We ask OpenAI not to store the requests; OpenAI and Google process them under their own privacy policies. Translations are cached only in your browser. Nothing is sent while translation is off (Alt+Shift+D toggles it).

What we never do

• We do not sell your data or transfer it to third parties, except to the service providers listed below, only to perform the feature you use.

• We do not use your data for advertising, credit decisions or any purpose unrelated to the extension's features.

• We do not run analytics or tracking, and the extension contains no ads.

• We do not collect payment information; payments for access are arranged outside the extension.

Service providers

Our servers run on Cloudflare. If you enable notifications for OneBOX, Apple or Google push services deliver them, encrypted. The creator platforms you use receive your actions directly from your browser under their own privacy policies. If you use OneLang, OpenAI and, as a fallback, Google translate the lines you send.

Your choices and rights

You can turn OneBOX, OneChat and OneLang off at any time, which erases their data on our servers. To access or delete the data linked to your account, write to 1onedeveloper1@gmail.com; we answer within 30 days. Deleting your account erases everything our servers keep about it, including your chatters' seats, their encrypted reports and your translation counts. Uninstalling the extension deletes everything stored in your browser.

Changes

If what ONE does with data changes, we will update this page and its date before the change ships.
