Privacy

Sell Thru is an independently operated, private item-research app. Updated September 24, 2026.

Accounts

Clerk handles sign-in, passwords, email verification and sessions. When you continue with Google, your account identity, basic profile and email are used for authentication and account recovery; we do not request access to your Gmail messages. Our backend stores an account identifier and access settings. Connecting eBay adds an encrypted seller credential or a hashed sign-in identifier; we never receive your eBay password. Apple credentials, when used, are encrypted for account-deletion revocation.

Google Sign-In also processes identifiers and IP addresses, including approximate location for fraud prevention. Its published software declarations include contact/profile data and device/usage data for analytics. Sell Thru does not request phone numbers or device-location permission. See the Google Sign-In data-use guidance and SDK privacy declarations.

Searches and photos

Submitted search terms and barcodes go to eBay and SoldComps for listing results. Amazon product identification sends the product's ASIN and marketplace to SearchApi, then uses the identified product's search phrase for eBay research. Compact product identities are cached for at most 12 hours. Supported Amazon inventory labels are sent to FNSKUtoASIN (F2A) to find the public ASIN. We retain compact, shared mappings of a hashed label to its ASIN without an automatic expiry; they contain no account identity, label photo or scan history and can be corrected or removed. F2A receives the label text and handles it under its privacy policy. A deliberate Lens search sends one compressed photo through temporary private Cloudflare storage to SearchApi for Google Lens processing. Research results are cached for at most 12 hours. Temporary Lens photos are deleted after processing, with a one-day expiration backstop. Providers handle submitted data under their own policies; deleting our copy does not establish deletion from their systems.

Saved items and drafts

Items you save retain their title, query, any confirmed public product identity and an optional small thumbnail until you delete the item or account. Drafts retain the fields and compressed item photos you choose. A connected eBay account also has a compact listing cache; opening an editor retains the selected listing fields. Disconnecting or deleting your account removes that cache. Ended cached listings without a linked editor expire after 30 days. Listing images are fetched directly from providers; we do not archive them. Temporary camera frames stay on your phone and are never uploaded. Unsynced edits remain on your phone until synchronized or deleted.

Subscriptions

Apple handles subscription payments. We store an account-linked purchase identifier, subscription status, billing dates and search allowance to provide access and restore purchases. We do not receive your card or bank details. Billing periods are removed after 90 days unless still needed by an active subscription or pending search. Account deletion removes our subscription records; it does not cancel Apple's billing. Manage or cancel your subscription in your Apple Account settings.

Security and deletion

Cloudflare hosts the backend, database and private images. We use bounded request, security and quota records without storing a browsing or photo history. We do not sell personal data or use advertising trackers. In the app, open Account > Delete account to request deletion. Resolve pending eBay listing actions first. Deleting this app account leaves your eBay listings active. Cleanup can take time for interrupted uploads; previously issued image links expire within five minutes. Short deletion records prevent old requests from recreating deleted data.

If an Apple token could not be retained, account deletion still proceeds; you can also revoke the app under Sign in with Apple in your Apple Account settings.

Contact

Email support@sellthruapp.com for help or privacy requests. In-app tickets send your selected category, message and verified account email to our support inbox. We keep a compact account-linked ticket receipt to prevent duplicates and abuse and send an acknowledgment email. Support correspondence is stored separately from app accounts, with private attachments and access restricted to the operator. Messages remain until removed; Trash is deleted after 30 days.
