Privacy policy

Updated November 9, 2026. This policy describes the current GrinHug preview service. Contact support@grinhug.com with privacy questions or a request to delete your account, saved videos or records.

Account information

When you sign in with Google, we verify your identity and store your Google account identifier and verified email address. We use this information to maintain your account, associate your credits and generations with you, and let you access your records on another device. We request basic sign-in information. We store no Google password.

Photos, prompts and generated videos

Choosing a photo first displays it in your browser. When you confirm a real generation, GrinHug sends a resized copy of the photo and your motion description to KIE, the generation provider. KIE processes these inputs and returns a result or an error. Completed videos are saved in private object storage and served through an account-authenticated download route.

Generation records include task identifiers, status, timestamps, model and credit cost. Credit activity records grants, debits and refunds. The selected photo and motion description are excluded from browser local storage. The browser may retain design settings, sample selections and a request identifier to handle retries.

Service providers

Google supplies sign-in. Cloudflare hosts the site, processes requests and stores generated videos. Supabase stores GrinHug account, session, task and credit records in separate application tables. KIE processes generation inputs and outputs. GrinHug uses Google account information for authentication and account records. Google account information is excluded from model-generation requests.

KIE currently states that generated media is retained for 14 days and task metadata for two months. Its processing and retention rules also apply to data sent for generation. See the provider documentation linked below.

Storage and deletion

Account records and saved results currently remain until removed. The preview has no automatic seven-day deletion schedule. You can request deletion at support@grinhug.com using your account email address. We may ask you to verify account ownership before processing the request. Download videos you want to keep.

Cookies and security

GrinHug uses secure, HTTP-only cookies for a seven-day sign-in session and a short-lived sign-in challenge. Signing out revokes the current session. Account routes restrict access to the signed-in account's records. Service providers process connection and security information needed to operate their services. The current preview contains no advertising or analytics integrations.

Your choices and updates

You can sign out, choose which photos to submit and contact support to request access, correction or deletion. We update this page when the service's data handling changes. Public examples use prepared sample artwork; account videos require authenticated access.
