Privacy Policy

What Arck does

Arck helps you list clothing across resale marketplaces (eBay, Depop, Grailed, Poshmark) and tracks your sales. To do that, it stores the data you put into it and talks to the marketplaces on your behalf.

Data we store

• Account data. Your email address and a hashed password. If you sign in with Google, we receive your email address and Google account ID, and nothing else.
• Listing data. Photos, titles, descriptions, prices, measurements, and sale records you create. Photos are stored on our cloud storage so they can be published to marketplaces.
• Marketplace connections. Tokens that let Arck publish and delist on your behalf. These are encrypted at rest. We never store marketplace passwords.
• Billing. Payments run through Stripe. We store your subscription status, never your card number.
• Diagnostics. Error reports (message, stack trace, app version) so we can fix bugs. No advertising identifiers, no third-party analytics, no ad networks.

How Arck knows something sold

Through each marketplace: eBay’s own API for eBay, and the Arck Chrome extension reading your own signed-in seller pages on the others. Arck does not read your email and requests no mail permissions from any provider. Sale detection on the extension-driven marketplaces runs in your own browser, while it is open, not on our servers.

Camera, photos, and AR

The iOS app uses your camera to photograph items, scan pairing and label QR codes, and measure garments in AR. Photos you take are uploaded to your account. AR measurements are processed on-device; only the resulting numbers are uploaded. Nothing from your camera is collected in the background.

Who else processes your data

Arck uses these providers to run the service. Each receives only what its job needs, and none of them is permitted to use your data for their own purposes.

• Vercel(United States) — hosts the web app and API. Processes every request you make.
• Turso— hosts the database holding your account, listings, and sale records.
• Cloudflare— stores your listing photos (R2), and provides DNS and email routing for arck.store.
• Anthropic— drafts listing details from your item photos. Photos sent for this purpose are not used by Anthropic to train models under the terms we operate on.
• SerpApi— runs the optional Google Lens price lookup. When you ask for comparable prices on a photo, that photo is sent to SerpApi. If you never use the lookup, no photo goes there.
• Stripe— takes payment and holds your card details. We never see your card number.
• Resend— delivers account email such as password resets and sale notifications. Receives your email address and the message.
• Sentry— receives crash and error reports, which can include your account ID and the request that failed.
• Google— only if you use “Continue with Google”, and only for sign-in. Arck requests theopenid and email scopes and no others.

The marketplaces you connect (eBay, Depop, Grailed, Poshmark) receive the listings you choose to publish. They are your accounts, governed by their own privacy policies.

Where your data lives

Arck is operated from the United States and the providers above store and process data in the United States. If you use Arck from outside the US, your data is transferred there.

What we don’t do

• We don’t sell your data.
• We don’t run ads or share data with ad networks.
• We don’t track you across other apps or sites.
• We don’t read your email.

Deleting your data, and getting a copy

Deleting a listing removes its photos and records. To delete your account and everything in it, or to request a copy of your data, email lucca.walls@arck.store and we’ll complete it within 30 days. Deletion covers your listings, photos, marketplace tokens, and account record; it does not retract listings already published to a marketplace at your direction, which you delist or sell through that marketplace.
