Privacy Policy

Last updated: 30 October 2026

Flip ("we", "us", "our") is developed by Ben Copeman (hello@useflip.co.uk), an individual developer based in the UK. This policy explains what data Flip collects and how it's used.

What we collect

• Account info - your email address (and name, if you add one), via our authentication provider (Clerk), when you sign in.
• Photos you scan - sent to our AI provider (Anthropic) to analyze the item and estimate resale value. Photos are processed in real time and are not stored on our servers afterward - they're saved only on your own device (and your camera roll), so they remain accessible in your scan history even if you're offline.
• Usage data - your credit balance and how many scans you've used, stored on our servers so we can apply the right cost to each scan.
• Anonymous device ID - a random identifier generated on your device before you sign in, used to apply fair-use rate limits and your one free scan. If you later sign in, this ID becomes associated with your account.
• Price alerts - if you set a price alert, the item name and target price you choose are stored on our servers, tied to your account, so we can re-check the market and notify you.
• Push notification token - if you enable notifications, we store a device token (via Expo's push service) so we can send you price alerts and notices about your account (for example when your credit is running low). Occasional selling tips and offers are only sent if you say yes to "Selling tips and offers" in the app - we store that choice, and you can change it any time in Account → Tips and offers. You can turn off all notifications in your phone's Settings.
• Emails - we send occasional emails about Flip, such as a thank-you after a purchase, a reminder that you have credit waiting, or selling tips and offers. Every one has an unsubscribe link, and once you unsubscribe we don't email you again.
• Purchase data - if you top up your credit balance, payment is handled entirely by Apple/Google and our billing provider (RevenueCat) - we never see your card details.
• Live pricing data - to show comparable listings, we query eBay's public listings API using details from your scan (not your personal information).
• Crash and error data - if the app crashes or hits an error, basic diagnostic information is sent to our crash-reporting provider (Sentry) to help us fix it.
• Scan records - for each scan we keep the item name, condition, the price Flip gave and the eBay prices it was compared with, so we can check and improve pricing accuracy and build up Flip's own picture of what items are worth. These records aren't linked to your account and don't include your photos, so we keep them long-term, and they stay if an account is deleted.
• Message records - when we send you an email or notification (for example a price alert), we keep a record of what was sent, to whom, and whether it was delivered, for 90 days, so we can make sure messages arrive. To make sure we never send you the same email twice, we also keep a one-way coded version of your email address that can't be turned back into the address. These are deleted if you delete your account.
• Country and language - the country and language you choose in the app, so prices, emails and notifications come in the right currency and language.
• App usage statistics - which screens you open and which features you use (for example, that a scan was made or a top-up bought), with a random ID created only for this, your app version, and the country and language you chose. It isn't linked to your account, your email or the device ID above, and doesn't include photos or item names. If you mark a tracked item as sold and enter what it sold for, that price, Flip's price for it and where it sold are included, so we can measure how accurate Flip's prices are. Kept for 90 days. You can switch it off in Account.
• Sale reports - when you mark a tracked item as sold and enter what it sold for, we also keep that sale price with the item's name and condition, Flip's price for it, where it sold and the country you chose, to make Flip's prices more accurate. Like scan records, these aren't linked to your account, your device or the usage statistics ID and don't include photos, so we keep them long-term, and they stay if an account is deleted. They're sent with the usage statistics, so none are kept if you've switched those off.
• IP address - when you scan without signing in, we briefly keep your IP address to stop the free scan being abused, and delete it after 2 days. IP addresses are also used for daily fair-use limits, kept for up to 7 days.

What we don't do

• We don't sell your data to anyone.
• We don't store your photos on our servers after analyzing them.
• We don't share your email or scan data with anyone besides the service providers listed above, who process it only to run the app (Clerk for sign-in, Anthropic for analysis, RevenueCat for payments, Sentry for crash reports, Expo for notification delivery, Resend for sending emails, Vercel for hosting our servers, and Neon for our database).

Why we use your data

UK data protection law asks us to say which legal reason we rely on for each use:

• To run the app you signed up for (your account, scans, credit balance, purchases, price alerts and notices about your account) - because it's needed to provide the service you asked for.
• To keep Flip working, safe and accurate (fair-use limits, stopping free-scan abuse, crash reports, scan records, message records and usage statistics) - because we have a legitimate interest in running a reliable app and improving its prices. You can switch usage statistics off in Account.
• Selling tips and offers by notification - only with your consent, which you can withdraw any time in Account → Tips and offers.
• Occasional emails about Flip - because we have a legitimate interest in telling people who use Flip about it. You can unsubscribe from any email, for good.

Where your data is processed

Our database is in London. Some of our service providers (such as Anthropic, Clerk, RevenueCat, Expo, Resend and Vercel) are based in the United States, so your data may be processed there. When that happens we rely on the safeguards UK data protection law allows, such as the UK-US data bridge or the UK's approved contract terms for international transfers.

Your choices and rights

You can permanently delete your account and all associated server-side data at any time from within the app (Account → Profile → Delete Account), or by visiting our account deletion page if you no longer have the app installed. Scan history saved on your device can be cleared from within the app at any time. You can turn off notifications in your device settings, and usage statistics in Account.

You also have the right to ask for a copy of the data we hold about you, to have it corrected or deleted, to object to or restrict how we use it, and to receive it in a portable format. Email hello@useflip.co.uk and we'll reply within one month.

If you're unhappy with how we've handled your data, you can complain to the UK's Information Commissioner's Office (ICO) at ico.org.uk or on 0303 123 1113. We'd appreciate the chance to sort it out first, so please contact us before you do.

Flip isn't directed at children, and we don't knowingly collect data from anyone under 13.
