6. Local-First Architecture
Our products are designed with a local-first architecture. This means:
- Your personal content (documents, notes, financial data, fitness records, etc.) is stored only on your device by default.
- No account creation is required to use the core features of our applications.
- No personal content is uploaded to our servers or to any third-party servers without your explicit, informed consent.
- Encrypted local databases (using AES-256 encryption) protect your data on device.
- Optional cloud sync features (where available) are explicitly opt-in and use end-to-end encryption.
The only data that may leave your device are: (a) anonymous usage analytics you have explicitly opted into, and (b) data necessary to display advertisements in free apps (subject to the controls described in Sections 7-10).
7. Advertising & Monetization
Some of our free applications display advertisements to support ongoing development. This section explains in detail how advertising works in our applications.
Important: Advertising is only present in our free applications with ad-supported tiers. Our paid applications and paid features contain no advertising. You can always upgrade to remove ads while supporting independent development.
7.1 How Advertising Works
Our applications integrate with third-party advertising networks (collectively, "Ad Partners") that deliver, measure, and optimize advertisements within our apps. When you view or interact with an advertisement, certain information may be shared with the Ad Partner to deliver the ad, measure its effectiveness, and (in some cases) personalize future advertising.
7.2 Information Shared with Ad Partners
Depending on your device settings, operating system, and the specific Ad Partner's policies, the following information may be collected when an ad is displayed:
- Advertising ID (Apple's Identifier for Advertisers, or IDFA, on iOS)
- Device make, model, and operating system version
- Carrier and country/region (for ad relevance and regulatory compliance)
- Language and locale settings
- Screen size and resolution
- App version and session timestamps
- Ad interaction events (impressions, clicks, video views, completions)
- IP address (typically truncated or hashed)
- Non-personal contextual signals (e.g., current app screen, general activity category)
7.3 Your Control Over Advertising Data
You have meaningful control over advertising data:
- iOS: Open Settings > Privacy & Security > Tracking. Toggle "Allow Apps to Request to Track" off, or grant/deny tracking on a per-app basis.
- iOS: Settings > Privacy & Security > Apple Advertising. Toggle "Personalized Ads" off to limit ad personalization.
- Reset Advertising Identifier: You can reset your IDFA at any time via iOS Settings, which will cause future ad requests to receive a new, unlinked identifier.
When you opt out of tracking, our Ad Partners are instructed (by Apple's App Tracking Transparency framework) not to combine device data with third-party data for personalized advertising.
8. AdMob Integration (Google)
Our applications integrate Google AdMob, one of the world's largest mobile advertising platforms, operated by Google LLC. This section describes specifically how AdMob operates within our apps.

- App information: bundle ID, app version, session start/end
- Ad interaction data: impressions, clicks, video starts/completions
- User consent signals (e.g., GDPR consent status)

8.3 Google Account Linking
If you are signed into a Google account on your device and have not opted out of ad personalization, Google may link advertising activity to your Google account. You can manage this in your Google Account Ad Settings.

Google's use of advertising data is governed by the Google Privacy Policy and the Google Advertising Policies for Partners.
