Privacy Policy

Penzel for iOS · Last updated: 2026-05-23

This Privacy Policy explains how the Penzel iOS app ("Penzel", "we", "the app") handles your information. The short version: Penzel does not collect personally-identifying data. The only information leaving your device is anonymized crash reports (Section 3) when the app crashes. Usage analytics are disabled in this version (Section 4).

1. Information We Do Not Collect

Penzel does not collect, process, or transmit any of the following:

• Your name, email address, phone number, or any other identifying contact information
• Your location, including precise or approximate GPS data
• Your photos, camera roll, or any media on your device
• Your contacts, calendar, or any other personal data Apple's APIs make available
• The Advertising Identifier (IDFA) or any cross-app advertising data
• Browsing history or activity outside the Penzel app
• Personally-identifying behavioral data — what you tap, what you view, what you search for inside the app

Penzel uses one Google Firebase service for technical purposes — Crashlytics for crash reporting (Section 3) — which does not collect data that can identify you personally. The Firebase Analytics SDK is linked but data collection is disabled in this version (Section 4).

2. Information Stored Locally on Your Device

The app stores the following data only on your device, never transmitted anywhere:

• Favorite recipes and diagnostics — items you save for quick access, stored in Apple's local SwiftData database
• Daily usage counters — the count of paint conversions used today (for the free-tier 5/day limit), reset each calendar day
• Anonymous device identifier — a per-install random identifier (UUID) generated locally to gate free-tier usage. Never transmitted, regenerated if you reinstall the app
• Purchase entitlement — whether you have unlocked Full Access via the in-app purchase, managed by Apple's StoreKit

You can clear all of this data at any time by uninstalling Penzel.

3. Crash Reporting (Firebase Crashlytics)

Penzel uses Firebase Crashlytics, a Google service, to automatically collect anonymized crash reports when the app crashes unexpectedly. We use this data solely to identify and fix bugs that affect real users.

What is transmitted when a crash occurs:

• The crash stack trace and exception type
• Your device model (e.g. "iPhone 16 Pro") and iOS version
• The Penzel app version that crashed
• An anonymized installation ID generated by Firebase — not linked to your Apple ID, name, or any other personal identifier
• Approximate region, derived from your IP address at the time the crash report is sent; the IP itself is not stored

What Crashlytics does NOT collect:

• Your name, email, phone number, or any contact information
• Your precise location or GPS data
• The Advertising Identifier (IDFA)
• Any content you viewed, searched for, or saved as a favorite inside Penzel
• Any data that would let us or Google identify you personally

4. Analytics (Disabled in This Version)

The Firebase Analytics SDK is linked in the app bundle, but data collection is disabled (the SDK's IS_ANALYTICS_ENABLED setting is set to false). No usage events, screen-view events, or session data are sent to Google for analytics purposes.

• No Advertising Identifier (IDFA) is collected — the app does not link FirebaseAnalyticsIdentitySupport and does not show an App Tracking Transparency prompt
• No cross-app behavioral tracking is performed
• No screen-view events, tap events, or feature-usage events are logged or transmitted
• No demographic targeting or audience segmentation is performed

Any device information Firebase collects in connection with crash reporting (Section 3) is the only telemetry leaving your device. Google's handling of crash data is additionally governed by Firebase's Privacy Information and Google's general privacy policy.

If a future version of Penzel enables analytics, this Privacy Policy will be updated before that change ships and the App Store privacy disclosures will be updated accordingly (Section 9).

5. In-App Purchase

Penzel offers one optional in-app purchase: Penzel Full Access ($9.99 USD, one-time, non-consumable). This purchase is processed entirely by Apple's StoreKit framework. Apple — not Penzel — receives and processes your payment information. Penzel never sees your credit card, billing address, or Apple ID.

Refunds are handled by Apple per their App Store refund policy. We have no ability to issue or deny refunds directly.

6. External Links

Each recipe and diagnostic entry in Penzel includes a source attribution link to its origin — typically a public article on Goonhammer. When you tap a source link, the article opens in an in-app Safari browser (SFSafariViewController). Safari handles its own privacy and may set its own cookies according to your Safari settings; we have no visibility into your browsing within those sessions.

7. Children's Privacy

Penzel is suitable for ages 4+ and does not knowingly collect personal information from anyone, including children. The data collection described in Sections 3 and 4 is anonymized and does not include any personal identifiers that could be used to identify a child specifically.

8. International Users (GDPR, CCPA, etc.)

Penzel collects no personally-identifying data. The aggregated, anonymized data described in Sections 3 and 4 is most-regulator-treated as non-personal data when it cannot be linked to an individual (as is the case here). You retain all the rights guaranteed by GDPR, CCPA, and similar laws:

• Right to access: personal data on your device is visible in the app; we hold no other personal data about you.
• Right to deletion: uninstall the app to clear all on-device data. Anonymous crash and analytics records cannot be linked back to a specific user, and so cannot be selectively deleted on request — they remain in Google's aggregate dataset.
• Right to portability: there is no personal data to port.
• Right to opt out of sale of personal data: we have no personal data to sell.

9. Future Features Requiring Data Collection

If a future version of Penzel introduces features beyond the current crash reporting and anonymous analytics that require additional data collection — for example, optional cloud sync, an online Q&A feature, or behavioral targeting — we will update this Privacy Policy before shipping the change, and any new data collection will be clearly disclosed and (where appropriate) require your opt-in consent.

10. Changes to This Policy

If we change this Privacy Policy materially, we will update the date at the top of this document and (if the change introduces new data collection) prompt you in-app to review the changes. Continued use of Penzel after the effective date of a change constitutes acceptance of the updated policy.
