Cookies & storage

Current application

MyFittys uses browser storage for sign-in and temporary application state, including checkout choices and chat preferences. Account records, favourites, saved messages and membership information are also stored on the server. That database storage is explained in the privacy notice.

Sign-in and hosting

ChatGPT sign-in and the hosting layer may use authentication, session and security cookies or comparable storage. These are managed outside the MyFittys application code. A full live cookie inventory, including provider, name and duration, is still required before this draft becomes a launch-ready notice. We do not claim that the entire hosted service is cookie-free.

Optional tracking

The owner’s Harry referral link uses referral tracking. Creator affiliate links remain inactive until the creator programme is activated. Following an active referral link uses a first-party referral cookie, __Host-mf-ref, for up to 30 days. It holds an opaque random reference and is removed after attribution to a signed-in account. A hashed reference links an eligible new signup to the referring account; the referral dashboard shows aggregate visit and signup counts, not customer identities or conversations.

TikTok advertising measurement stays off until you select Accept advertising. You can reject optional tracking or change your choice using Cookie settings in the footer. See Optional TikTok advertising measurement below for details.

Google Fonts

The home page retrieves font styles and files from Google Fonts. Those requests expose connection information, including your IP address, to Google. This is distinct from claiming that Google Fonts sets advertising cookies. See Google’s privacy policy for its processing.

Managing your browser

You can inspect, block or clear site cookies through your browser’s privacy settings. Blocking essential sign-in storage may prevent account features from working. Clearing cookies does not remove messages or other data from the MyFittys database. Use the chat deletion control or the privacy contact route for stored content.

Notice status

Draft reviewed 11 September 2026. Cookie names, lifetimes and provider behaviour must be checked in the live sign-in flow before public launch.

Optional TikTok advertising measurement

Updated 26 September 2026. With your consent, MyFittys loads the TikTok Pixel to measure page visits and confirmed initial subscription purchases, attribute advertising and improve campaigns. TikTok receives browser and device information (including IP address), page URL and referrer, advertising identifiers and, for a purchase, its amount, currency and a pseudonymous event reference. We do not deliberately include chat messages, selected character names, account emails, photographs or payment-card details in advertising events. Advanced matching is not implemented by MyFittys.

Reject optional cookies to use MyFittys without this advertising pixel. Change or withdraw your choice using Cookie settings in the footer. Withdrawal stops future pixel loading; it does not undo information previously received by TikTok. Our consent preference is stored for up to six months. TikTok may use first-party cookies such as _ttp and ttcsid, alongside its own advertising cookies. Their use and processing outside your country are described in TikTok’s privacy policy and TikTok’s cookie information. Local purchase-event references prevent duplicate reporting, and a pending checkout reference in session storage expires after 48 hours.

Fitty games and progress

When you open Fitty games, an essential first-party cookie, __Host-mf-games, remembers a random browser identifier for up to one year. It supports safe game requests. Games require a paid plan. Signed-in progress, completed games, streaks and unlocked media are saved to your account. Any historical trial progress can be linked to your account when you sign in.

We record game activity to understand usage and improve the feature. Abuse checks use a daily keyed hash of the connection address; the games database does not store the raw IP address. Game events do not include chat text, photographs, payment details or email addresses.

Optional ChatGPT Ads measurement

With advertising consent, MyFittys loads OpenAI’s Measurement Pixel to measure page visits, completed registrations, checkout starts and Stripe-verified initial paid subscriptions. OpenAI receives browser and connection information, advertising identifiers and subscription amount, currency and a pseudonymous event reference. We do not send chat text, model selections, account emails or payment-card details in these events. OpenAI’s automatic advanced matching can detect supported customer information on the page and hash it in the browser before sending it for ad attribution; raw matching information is not sent.

Reject optional advertising or withdraw consent in Cookie settings. Tracking waits for a new advertising choice covering OpenAI and TikTok. OpenAI’s first-party __oppref attribution cookie lasts up to 30 days and __obref browser-reference cookie up to 365 days; withdrawal removes these cookies. A pending checkout reference expires after 48 hours. Completed-event references prevent duplicates. See OpenAI’s privacy policy.
