Privacy Policy
RunFiller is a personal comic-collection tracker. This policy explains what data we collect, how we use it, and your rights.
TL;DR
We collect the minimum data needed to make the app work: what comics you own, what you want, and what you scan. We don't sell your data, we don't share it with advertisers, and we don't track you across other apps or websites. Your data is stored on cloud infrastructure in the United States.
Who We Are
RunFiller is an iOS application developed by Baz Studios LLC, a Delaware limited liability company.
You can reach us at runfiller@bazstudios.com.
What We Collect
Information you provide directly
- Your collection: which comic series you track, which issues you own, which issues are on your wantlist
- Scan activity: barcodes you scan with the camera, and (optionally) cover photos you submit for image-based matching
- Settings preferences: your collector identity choice (Cover A only, all variants, etc.) and other in-app preferences
Information collected automatically
- Device identifier: a randomly-generated identifier assigned by Apple/Expo so we can associate your collection data with your device
- App diagnostics: crash reports, app version, iOS version. Used to fix bugs. No personally-identifying information attached.
Information we DO NOT collect
We do not collect:
- Your name, email address, phone number, or physical address
- Your location (GPS, IP geolocation, etc.)
- Your contacts or calendar
- Health, financial, or biometric data
- Browsing history outside the RunFiller app
- Any data for cross-app or cross-website tracking
How We Use Your Information
- To save your collection across app sessions
- To match a scanned barcode or cover photo to a specific comic issue
- To show you progress against runs you're tracking
- To diagnose crashes and improve app stability
We do not use your information for advertising, marketing emails, or any commercial purpose beyond making the app function.
How Your Information Is Stored
Your collection data is stored in Neon Postgres (US-East region). Cover images used for scan matching are processed by Google Cloud Vertex AI (US-Central region) — images are sent for analysis and discarded after; we do not retain your scan photos. The application backend runs on Fly.io in the US.
All providers maintain industry-standard security practices including encryption in transit (TLS) and at rest.
Who We Share Your Information With
We share your information only with the cloud service providers needed to operate the app:
- Neon (database hosting)
- Cloudflare (image cover hosting)
- Google Cloud (image matching via Vertex AI)
- Fly.io (application backend hosting)
- Apple (App Store distribution, push notifications if enabled later)
We never sell, rent, or trade your personal information.
If you tap an in-app link to an external site (e.g., an eBay listing to acquire a missing issue), that third party operates under their own privacy policy.
How Long We Keep Your Information
We retain your collection data for as long as you continue to use the app. If you delete the app or stop using it for an extended period (12+ months), you may request deletion of your data by emailing runfiller@bazstudios.com. We will delete your data within 30 days of verifying your request.
Your Rights
You have the right to:
- Access the data we hold about you (request via email)
- Correct inaccurate data
- Delete your data (request via email; effective within 30 days)
- Export your collection in a portable format (CSV or JSON)
If you're in California (CCPA), the European Union (GDPR), or another jurisdiction with specific data rights, contact us and we will honor applicable rights.
Children's Privacy
RunFiller is not directed at children under 13 and we do not knowingly collect information from children under 13. If you believe we have collected such information, contact us and we will delete it.
Cover Imagery
Comic cover images displayed in the app are sourced from publicly-available promotional materials provided by publishers, distributors, and retailers. These images are used solely to help you identify issues in your collection. They are not collected from you and we do not associate them with your personal data.
Cookies and Tracking Technologies
The RunFiller iOS app does not use cookies or cross-app tracking technologies. We do not participate in the Apple Tracking Transparency (ATT) framework's tracking permission requests because we do not track you across other apps or websites.
Changes to This Policy
We may update this Privacy Policy from time to time. Material changes will be communicated via an in-app notice. The "Last updated" date above will always reflect the most recent revision.
