Terms of Service

Version 2026-07-30 · Effective 30 July 2026

These terms are a contract between you and us covering your use of FlipTracker. The short version: your records are yours, we use them to run the app for you and for nothing else, and you can take them with you or delete them whenever you like.

1. Agreement to these terms

By creating an account or using FlipTracker (the "Service"), you agree to these Terms of Service. If you do not agree, do not use the Service.

The Service is operated by Matthew Viereck ("we", "us", "our"). You must be at least 18 years old, or the age of majority where you live, to have an account.

2. What FlipTracker is

FlipTracker helps resellers record inventory, acquisition costs, sale prices, fees and expenses, and see the resulting profit. We may add, change or remove features over time.

We are not affiliated with, endorsed by, or partnered with eBay, Poshmark, Mercari, Depop, Facebook, OfferUp, Amazon, or any other marketplace. Those names are used only to describe where an item was sold.

3. Your account

You are responsible for keeping your password secure and for everything that happens under your account. Tell us promptly if you think someone else has access to it.

You must give accurate registration information and keep it current.

4. Subscriptions and billing

The Service has a free tier and one or more paid tiers. Paid subscriptions renew automatically at the interval you chose until cancelled.

Payments are processed by Stripe. We do not receive or store your full card details. Your use of Stripe's payment processing is also subject to Stripe's own terms.

You can cancel at any time, and cancellation takes effect at the end of the period you have already paid for. Except where the law requires otherwise, payments already made are non-refundable.

We may change prices. If we do, we will tell you before the change applies to you, and the new price takes effect at your next renewal.

5. Your data

"Your Data" means information you enter into the Service, or that the Service imports on your behalf from a file you upload. It includes item descriptions, acquisition costs, sourcing information, listing and sale prices, fees, shipping costs, photographs and associated dates.

You keep all ownership of Your Data. Nothing in these terms transfers ownership of Your Data to us.

6. What we do with your data, and what we don't

You give us permission to host, store, copy, transmit, display and process Your Data so that we can provide, maintain, secure and support the Service for you. That permission exists for one purpose: showing you your own numbers.

This permission ends when you delete the relevant data or your account, subject only to the backup retention periods described in our Privacy Policy.

If we ever want to use Your Data for a genuinely different purpose, we will ask you first and you will be free to say no.

7. Imported files

If you upload a sales report exported from a marketplace, you confirm that you have the right to do so and that doing so does not breach your agreement with that marketplace.

Imported data is treated exactly like anything else you type in: it is yours, it is used to show you your own figures, and it is deleted when you delete it.

8. Acceptable use

You agree not to:

• use the Service for anything unlawful, or to record or facilitate the sale of goods you are not lawfully entitled to sell;
• upload malicious code, or attempt to gain unauthorised access to the Service, other users' data, or our systems;
• scrape, bulk-download or systematically extract data from the Service beyond your own data;
• resell or redistribute the Service or its outputs as your own product; or
• interfere with or place unreasonable load on the Service.

9. Not tax, accounting or legal advice

The Service can produce summaries and exports intended to help you prepare your records, including reports formatted for tax purposes. These are a convenience, not professional advice.

We do not verify that your records are complete or correct, and figures the Service produces depend entirely on what you have entered. You remain responsible for your own tax filings and for confirming your numbers with a qualified accountant or tax professional.

10. Availability, changes and termination

We aim to keep the Service running but we do not guarantee uninterrupted availability. We may modify or discontinue features, and we may suspend or close accounts that breach these terms.

You may close your account at any time from within the Service or by contacting us. If we close the Service entirely, we will give you reasonable notice and a way to export your data first.

11. Disclaimer of warranties

The Service is provided "as is" and "as available", without warranties of any kind, whether express or implied, including implied warranties of merchantability, fitness for a particular purpose, and non-infringement, to the fullest extent permitted by law.

We do not warrant that the Service will be error-free, or that fee calculations will match what a marketplace actually charges you. Marketplace fee structures change, sometimes without notice; always check your own payout statements.

12. Limitation of liability

To the fullest extent permitted by law, we are not liable for indirect, incidental, special, consequential or punitive damages, or for lost profits, lost revenue, or lost or corrupted data, arising out of or relating to your use of the Service.

Our total liability arising out of or relating to these terms or the Service will not exceed the greater of (a) the amount you paid us in the twelve months before the event giving rise to the claim, or (b) fifty US dollars.

Some jurisdictions do not allow certain limitations, so parts of this section may not apply to you.

13. Indemnity

You agree to indemnify and hold us harmless from claims, losses and expenses (including reasonable legal fees) arising from your breach of these terms, your misuse of the Service, or your breach of any marketplace's terms in connection with data you bring into the Service.

14. Changes to these terms

We may update these terms. When we make a material change we will bump the version, publish the updated terms here, and ask you to accept them the next time you use the Service.

Previous versions are retained so that it is always possible to establish which text you accepted and when. Continuing to use the Service after a change takes effect means you accept the updated terms.

15. Governing law and disputes

These terms are governed by the laws of the State of Pennsylvania, without regard to its conflict-of-laws rules. You and we agree to the exclusive jurisdiction of the state and federal courts located in Pennsylvania for any dispute that is not resolved informally.

Before filing anything, please contact us — most problems are faster to fix by email.
