Privacy Policy

GemGrader is developed by Komohouse. This policy explains how the GemGrader iOS app handles your data.

Card images:When you grade a card, photos of the front and back are captured by your device's camera. These images are sent to Google's Gemini API for AI-powered condition analysis. Google processes these images transiently and does not retain them after the request completes. We do not store your card images on our servers.

Grading records:Your grading history (card name, grade, sub-grades, and card images) is stored locally on your device using Apple's SwiftData framework. If you have iCloud enabled, this data syncs to your personal iCloud account via CloudKit. We cannot access your iCloud data.

Card pricing: We fetch pricing data from TCGGO (pokemon-api.com) and TCGdex. These requests include the card name and set information but no personal data.

Preferences: Settings like your preferred currency and grading company are stored locally on your device using UserDefaults. This data never leaves your device.

We do not collect your name, email address, location, device identifiers, or any other personal information. We do not use analytics, tracking, or advertising SDKs. We do not sell or share any data with third parties for marketing purposes.

Google Gemini API:Card images are sent to Google's Gemini 2.5 Flash model via our secure proxy server for grading analysis. Google's API terms apply to this processing. Images are not retained by Google after the request.

TCGGO (pokemon-api.com): Card names and set information are sent to retrieve market pricing. No personal data is included in these requests.

TCGdex: Card names and set information are sent to retrieve card metadata and images. No authentication or personal data is required.

Apple iCloud (CloudKit): If enabled on your device, grading records sync to your personal iCloud account. This uses Apple's CloudKit infrastructure and is governed by Apple's privacy policy.

All grading data is stored on your device and optionally in your iCloud account. You can delete individual records from the app at any time. Deleting the app removes all local data. iCloud data can be managed through your device's iCloud settings.

GemGrader does not knowingly collect personal information from children under 13. The app does not require account creation or collect personal identifiers.

We may update this policy from time to time. Changes will be reflected in the app and on this page.
