# Return YouTube Dislike Privacy Policy
|
|
|
|
Last updated: September 5, 2026
|
|
|
|
This policy describes version 4.0.5 and its matching backend release.
|
|
|
|
Return YouTube Dislike transmits only the data needed to provide its dislike-count, voting, abuse-prevention, and
|
|
optional premium features. It does not sell personal data or use it for advertising.
|
|
|
|
## Data required for the extension to work
|
|
|
|
- On registration, the extension generates a persistent random installation identifier and sends it to the Return
|
|
YouTube Dislike API. The identifier is not derived from or linked to a YouTube or Google account, but it is a
|
|
persistent identifier and is treated as personal data.
|
|
- When a YouTube video is opened, the extension sends that video's ID and, when available, its visible like count to
|
|
retrieve and improve the dislike estimate.
|
|
- When the user submits a Like, Dislike, or vote removal and vote submission is enabled, the extension sends the random
|
|
installation identifier, video ID, and selected action.
|
|
- API requests necessarily expose the network IP address and request time. The service uses this information for
|
|
security, abuse prevention, aggregate analytics, and operation of the API.
|
|
|
|
The extension does not send a YouTube account name, comments, private YouTube data, or the contents of unrelated web
|
|
pages. It does not maintain a separate local list of videos watched.
|
|
|
|
## Optional account and premium data
|
|
|
|
Patreon and GitHub sign-in are optional. The account flow starts only after the user selects a sign-in button and, in
|
|
Firefox, grants the separate authentication-data permission. The selected provider and the Return YouTube Dislike API
|
|
process the OAuth authorization response. The API returns the provider account ID, name, profile image,
|
|
account-access status, access tier, and a Return YouTube Dislike session token as applicable to that provider. GitHub
|
|
sign-in may also return an email address. Patreon sign-in does not request or return email, account-status fields,
|
|
or connected social accounts; the name and profile image identify the signed-in account in the popup. To
|
|
determine Patreon access, the matching backend uses currently entitled tier IDs. It does not request or use membership
|
|
amounts, charge dates or status, lifetime payments, or patron status. The extension does not receive payment-card or
|
|
bank-account details.
|
|
|
|
Those account details and the session token are stored in browser extension storage and used to authenticate premium
|
|
analytics requests. The session token expires after 30 days. Signing out deletes the locally stored account details and
|
|
session token. Revoking Firefox's authentication-data permission clears that local account session and prevents further
|
|
account and premium requests. Pending responses cannot restore the session; the user must sign in again to resume it.
|
|
|
|
Patreon and GitHub process sign-in information under their own privacy policies. The extension never receives the
|
|
user's Patreon or GitHub password.
|
|
|
|
## Storage, retention, and sharing
|
|
|
|
The identifier, settings, and optional account session use browser extension sync storage, which may be synchronized
|
|
through the browser's sync service when the user enables it. The random installation identifier remains in extension storage until the extension data is cleared, registration is
|
|
reset, or the extension is removed. Confirmed vote records contain the identifier, video ID, vote, timestamp, and the
|
|
network address used for abuse controls. Registration and vote records are retained by the service while they are
|
|
needed to calculate results, maintain vote integrity, and prevent abuse; no shorter automatic deletion period is
|
|
promised.
|
|
|
|
Data is not sold or shared for advertising. It is processed by the Return YouTube Dislike service and its hosting and
|
|
network infrastructure providers, and by Patreon or GitHub only when the user chooses the corresponding sign-in flow.
|
|
|
|
## User controls
|
|
|
|
Firefox displays its built-in consent prompt before the required data is transmitted. Refusing the required consent
|
|
prevents installation or acceptance of the update. Vote submission can be disabled in the extension settings. Optional account access can be
|
|
declined or revoked without disabling ordinary dislike counts. Firefox private-window access is disabled.
|
|
|
|
Users can clear extension storage or remove the extension to delete locally stored data. Requests concerning service
|
|
data can be made through the project's support channels at https://returnyoutubedislike.com/help.
