RetroGrade Terms of Service
These Terms of Service ("Terms") govern your use of the RetroGrade mobile application ("the App"), provided by Erik May ("we," "us"). By creating an account or using the App, you agree to these Terms. If you don't agree, don't use the App.
1The service
RetroGrade lets you track a portfolio of graded/sealed video games, view market value estimates and trend data, browse live third-party marketplace listings, and set price alerts. A Premium subscription unlocks price data for platforms beyond the free tier (NES, SNES, N64).
2Not financial or investment advice
Read this carefully. All prices, valuations, trends, and estimates shown in the App — including the "Sealed Graded Estimate," valuation history, and any figure derived from public auction results, eBay, or any other third-party source — are provided for informational purposes only. They are estimates based on available market data and are not appraisals, offers to buy or sell, or investment, financial, or professional advice. Collectible values can be volatile, illiquid, and based on incomplete or unrepresentative data (for example, a valuation may be based on a small number of comparable sales, or on active asking prices rather than confirmed sales).
You are solely responsible for any decision to buy, sell, trade, or insure an item based on information in the App. We do not guarantee the accuracy, completeness, or timeliness of any price or valuation shown, and we are not liable for any financial loss resulting from your reliance on it.
3Accounts
- You must sign in via "Sign in with Apple" to use the App. You're responsible for keeping your Apple ID credentials secure and for all activity under your account.
- You must be at least 16 years old (or the digital-consent age in your jurisdiction) to use the App.
- You may request account deletion at any time — see the Privacy Policy, Section 5.
4Subscriptions and payment
- Premium is offered as an auto-renewing subscription (monthly or annual), billed through the Apple App Store or Google Play, at the price shown at time of purchase.
- Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel your subscription in your Apple ID or Google account settings — we do not process payments or issue refunds directly; refund requests go through Apple's or Google's own policies.
- Prices may vary by region and are set in App Store Connect / Google Play Console; the price shown in the App at checkout is the price sourced live from the store.
- We may change what's included in Premium or its price for future billing periods, with notice where required by law or store policy.
5Third-party data and services
Market data shown in the App is sourced from third parties, including public auction results (e.g., Heritage Auctions, Goldin) and eBay's Browse API. We don't control, and aren't responsible for, the accuracy of that third-party data, the availability of any listing, or the outcome of any transaction you make on eBay or any other marketplace. Links to eBay listings may be affiliate links, meaning we may earn a commission on purchases made through them at no additional cost to you.
6Acceptable use
You agree not to:
- Use the App for any unlawful purpose, or in a way that infringes anyone else's rights.
- Attempt to reverse-engineer, scrape, or interfere with the App or its backend services beyond normal use.
- Misrepresent your identity, or share your account with others.
- Use automated means to access the App outside the functionality we provide.
We may suspend or terminate accounts that violate these Terms.
7Intellectual property
The App, its design, and its original content (excluding third-party data and any trademarks owned by others) are owned by us or our licensors. Grading-company names and trademarks (e.g., PSA, WATA, VGA, CGC) referenced in the App belong to their respective owners and are used only to describe and identify real grading services and products — no affiliation with or endorsement by those companies is claimed or implied. Game titles, platform names, and any character or artwork references are the property of their respective rights holders.
8Disclaimers and limitation of liability
The App is provided "as is" and "as available," without warranties of any kind, express or implied. To the fullest extent permitted by law, we disclaim all warranties, including fitness for a particular purpose and non-infringement, and we are not liable for any indirect, incidental, special, or consequential damages, or for any loss of profits or data, arising from your use of the App — including any financial decision made in reliance on data shown in it (see Section 2). Our total liability for any claim relating to the App is limited to the amount you paid us in the 12 months before the claim arose, or $50, whichever is greater.
9Termination
You may stop using the App and delete your account at any time. We may suspend or terminate your access if you violate these Terms or if we discontinue the service, with notice where reasonably practicable.
10Changes to these Terms
We may update these Terms from time to time. We'll notify you of material changes in the App or by email before they take effect. Continuing to use the App after changes take effect means you accept the updated Terms.
11Governing law
These Terms are governed by the laws of the State of Ohio, USA, without regard to conflict-of-law principles, except where local consumer-protection law requires otherwise.
