Privacy Policy

Effective date: September 5, 2026 · Last updated: September 5, 2026

1. Overview

Aperture ("the App", "we", "us") is a contemplative practice app for attention training, intuition exercises, and self-tracking. This policy explains what data the App collects, how it is used, and what choices you have.

The short version: All your practice data (sessions, journal entries, streaks, settings) is stored locally on your device and is never transmitted to us. The only data that leaves your device is information collected by Google AdMob to serve ads, and only if you have ads enabled in Settings.

2. What data we collect

Data stored on your device only (not transmitted to us):

• Practice session results (mode, duration, target, scores)
• Journal entries you write
• Streak data and achievement progress
• App settings (theme, sound, notification time, ad preferences)
• Custom RV (remote viewing) target images you upload

Data collected by Google AdMob (only if ads are enabled):

• Google advertising ID (a resettable device identifier)
• Device information (model, OS version, screen size, language, country)
• IP address (truncated by Google)
• Ad interaction data (which ads were shown, clicked, or dismissed)
• Approximate location (derived from IP, not precise GPS)

AdMob data collection is governed by Google's Privacy Policy and the AdMob data usage policy.

Data we do NOT collect:

• Name, email, or any account information (Aperture has no accounts)
• Precise GPS location
• Contacts, photos, microphone, or camera (we only use the photo picker for custom RV targets)
• Crash reports or analytics (none enabled)

3. How we use data

On-device data is used solely to provide the App's features (showing your history, unlocking modes, displaying achievements). We do not have servers, so we do not process this data.

AdMob uses its collected data to:

• Select and serve ads
• Measure ad performance (impressions, clicks)
• Detect and prevent fraud
• Build anonymous audience segments (if you have personalized ads enabled)

4. Third parties (AdMob)

The App uses Google AdMob to display ads. AdMob may use the data described above in accordance with its own policies. We do not control AdMob's data practices.

Your choices with AdMob:

• Disable ads entirely: Settings → Ads & Sponsorships → Show sponsored content (off). This hides all banner and rewarded ads. Interstitials are also disabled.
• Opt out of personalized ads: Settings → Ads & Sponsorships → Personalized ads (off). This tells AdMob not to use your advertising ID for personalization. You will still see ads; they will be contextual only.
• Reset your advertising ID: On Android: Settings → Google → Ads → Reset advertising ID.
• Opt out of ads measurement: On Android: Settings → Google → Ads → Opt out of Ads Personalization.

5. Local storage

All your practice data, journal entries, and settings are stored on your device using the browser's localStorage and IndexedDB APIs. This data:

• Never leaves your device unless you explicitly export it (the App provides an export feature in Settings → Data).
• Is removed if you uninstall the App or clear App data.
• Is not accessible to us, the developer, or any third party (other than the platform's standard sandboxing).

If you back up your device or sync to a cloud service, the App's local data may be included in that backup. This is controlled by your device's backup settings, not by the App.

6. Your rights (GDPR / CCPA)

European Economic Area, UK, and Switzerland (GDPR):

You have the right to:

• Access the personal data we hold about you (we hold none; all is on your device)
• Rectify inaccurate data
• Request deletion of data
• Object to processing
• Request data portability (use the App's export feature)
• Withdraw consent at any time
• Lodge a complaint with your local data protection authority

Our legal basis for processing AdMob data is legitimate interest (serving relevant ads to keep the App free). You may object at any time by disabling ads or opting out of personalized ads.

California (CCPA / CPRA):

California residents have the right to:

• Know what personal information is collected (see Section 2)
• Request deletion of personal information
• Opt out of the "sale" of personal information (we do not sell data; AdMob's use of advertising ID may be considered a "share" under CPRA — you can opt out via Settings)
• Non-discrimination for exercising these rights

To exercise these rights, contact us at the address in Section 10. We will respond within 45 days.

Other jurisdictions:

If you have questions about your rights under other data protection laws (LGPD in Brazil, PIPL in China, etc.), please contact us.

7. Children's privacy

The App is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, contact us so we can delete it.

The App's settings include a "Not designed for children" disclosure, which is set in the Play Store listing. The App does not target child-directed treatment under COPPA.

8. Security

Because we do not collect or transmit your practice data, there is no server-side data to secure. Local data is protected by your device's standard sandboxing (Android App sandbox, browser profile isolation on web).

AdMob data is protected by Google's infrastructure security, described in Google Cloud Security.

No security measure is perfect. You use the App at your own risk.

9. Changes to this policy

We may update this policy. Changes will be posted on this page with an updated "Last updated" date. If changes are material, we will notify you through the App or this URL.

Change history:

• September 5, 2026 — Initial policy.
