Privacy Policy

Overview

Stelmar Labs operates Shelfie — Snap it. List it. Sell it. From shelf to sale. Shelfie is a mobile listing assistant (the "app") that helps you turn photos into AI listing drafts and post them to marketplaces. This policy describes what information the app and our online services collect and how we use it.

Sign-in and account data

You can sign in with Sign in with Apple and/or a mobile phone number (one-time SMS code). You may use either method alone, or link both methods to the same Shelfie account in Settings so either opens the same inventory.

• Sign in with Apple: we receive a stable Apple user identifier and, when Apple provides it, an email address (which may be a private relay address). We use this to create or restore your session and, when Apple marks the email as verified, may attach Sign in with Apple to an existing account that already uses that email.
• Phone number: when you use phone sign-in or link a phone in Settings, we store your number to deliver verification codes and associate it with your account.

SMS verification program

Phone sign-in and phone linking use a transactional SMS program. You opt in only when you request a code for a number you enter: review the SMS disclosure in the app, agree to the consent checkbox, and tap Send code. We do not send marketing or promotional SMS.

• How you opt in: start the phone number path in the app (sign-in or Settings → Link phone), enter your mobile number, check the consent box, and tap Send code.
• Message frequency: varies. You receive SMS only when you request a verification code.
• Rates: message and data rates may apply.
• Opt-out: reply STOP to our sender number. Reply HELP for help or email support@stelmarlabs.com.
• Data use: we use your phone number to deliver verification codes and secure your account.
• No sale or sharing of SMS opt-in data: we do not sell or share your mobile phone number or SMS opt-in consent data with third parties for their marketing purposes. We share data with our SMS delivery provider only as needed to send verification messages.

See our Terms of Service for the full SMS program terms, and Support for the opt-in flow and screenshots.

Photos and listing content

When you analyze photos, images are sent to our servers and forwarded to a third-party AI provider (OpenAI or Google Gemini, depending on configuration) to generate listing drafts. Photos are processed for that request. Listing text and photos are also stored on your device.

Cloud sync

When you are signed in, Shelfie backs up listing metadata and photos to our servers so you can restore them on a new device. Sync runs while you remain signed in. You can delete listings in the app at any time and sign out to stop cloud backup on that device.

Marketplaces and third parties

Shelfie helps you copy listing text and share photos so you can post on marketplaces such as eBay, Facebook, Mercari, and OfferUp. We do not post on your behalf. Anything you publish on a third-party platform is subject to that platform's terms and policies. Sign in with Apple is provided by Apple; use of that feature is also subject to Apple's terms and privacy practices.

Device and usage data

Our servers log structured events (errors, rate limits, authentication) for reliability. We may use a crash and error reporting service (Sentry) with technical diagnostics; we do not sell personal data. Server logs may include account identifiers and request metadata.

Account deletion

You can permanently delete your Shelfie account from Settings → Delete Account in the app. Deletion removes your account, linked sign-in methods (phone and Apple), sessions, cloud listing backups, and photos from our servers. Listing content you already published on third-party marketplaces is not removed by Shelfie. If you previously texted STOP to our SMS sender, we keep that opt-out so we do not message you again if the same number is reused.

Your choices

• Delete listings anytime in the app.
• Export a JSON backup from the inventory screen.
• Sign out to stop cloud sync on that device.
• Link phone and/or Apple in Settings when signed in.
• Delete your account from Settings to erase server-side data.
• Reply STOP to opt out of verification SMS.
