InStock lets you monitor product pages you choose and receive stock and price alerts from periodic checks. InStock is independent and is not affiliated with or endorsed by any retailer.
We do not collect card details, contacts or precise location, and we do not sell personal data.
We use Apple for notifications and purchases, Supabase for authentication and database hosting, Cloudflare for API hosting and scheduled jobs, RevenueCat for purchase status, Zyte to retrieve public product pages, Anthropic to extract stock information from those pages, and PostHog for operational analytics when enabled. Account details are not sent to Anthropic.
Earlier versions used InfluTo for creator access and referral attribution. InfluTo may hold install, device, referral and app-user identifiers previously provided to it. This version removes that integration; historical provider records are not erased by removing it. InfluTo accepts server-data deletion requests at hello@influ.to and retains attributed purchase and payout financial records for seven years. See InfluTo's deletion and retention information. Contact our support address below for help with historical data.
Watches remain until you delete them or delete your account. To delete your account, open Settings > Delete Account in InStock and confirm the request. If you signed in with Apple, confirm your Apple sign-in when asked so its authorization can be revoked.
Successful account deletion removes your InStock account, authentication record, tracked items and account-linked app records. A restricted cleanup record retains your account identifier and retry status while follow-up provider erasure requests are pending. Failed requests remain queued for retry; the cleanup record is removed after the required follow-up requests are accepted. A hashed confirmation receipt remains valid for 24 hours to recover an interrupted deletion response; expired receipts are removed by scheduled cleanup. These records contain no Apple credentials or raw session tokens.
Deletion requests are also sent to RevenueCat and, where applicable, PostHog. Those providers may continue processing accepted erasure requests after the app confirms account deletion. Signing out alone does not delete your account.
Deleting your InStock account does not delete your Apple Account or cancel an Apple subscription. Subscription billing continues until you cancel through Apple subscription settings.
