Privacy Policy

Last updated: September 5, 2026  ·  Applies to all apps by Engin Aytekin

This Privacy Policy describes how your information is handled across the following apps:

Summary

• No account, no login, no profile. We never collect your name, email, or phone number.
• Content you create stays on your device and is deleted when you uninstall the app.
• We collect app usage analytics, crash and diagnostic logs, device and installation identifiers, and your subscription status.
• That data is sent to a small set of service providers: PostHog (analytics), RevenueCat (purchase validation), Expo (app updates), and Apple / Google (notifications, distribution, payments).
• Two ad-supported apps — It Works - Manifest List and 55x5 - Manifestation Ritual — also share your device Advertising ID with Google for ads. The other seven apps contain no advertising.
• We do not sell your personal data.

Information We Collect

• Usage analytics — anonymous events such as screen views, features used, session length, and onboarding and paywall funnel steps. Collected via PostHog.
• Device and technical information — device model, operating system and version, app version and build, language, time zone, and screen dimensions.
• Diagnostics and crash logs — when the app hits an error, we log the error message, a stack trace, and basic device state so it can be fixed. Collected via PostHog.
• Purchase and subscription status — when you buy a subscription, your App Store or Google Play purchase receipt / token is sent to RevenueCat to verify it and to tell the app whether your subscription is active.
• Update checks — on launch, the app contacts Expo's update service to check for a JavaScript update. The request includes a random installation identifier, the platform, and the app's runtime version.
• Notification registration — if you enable reminders, the operating system's push service (Apple Push Notification service, or Firebase Cloud Messaging on Android) issues a device token; on Android, Firebase Cloud Messaging also registers a Firebase installation identifier with Google. Notifications are used only to deliver your own reminders and re-engagement nudges, never for third-party marketing.

Device or Other Identifiers

Several of the services above receive an identifier that is specific to your device or app installation:

• A random analytics identifier generated by PostHog
• A random customer identifier generated by RevenueCat
• A random installation identifier used by the Expo update service
• On Android, a Firebase installation identifier used by Firebase Cloud Messaging
• In It Works and 55x5 only, the device Advertising ID — see Advertising below

These identifiers let the apps function, count usage accurately, and — in the two ad-supported apps — show ads. They are never combined with your name, email, or contact information, because those are never collected.

Advertising (It Works and 55x5 only)

Two apps, It Works - Manifest List and 55x5 - Manifestation Ritual, are supported by ads served through Google AdMob. To serve and measure those ads, Google's advertising SDK collects your device Advertising ID together with standard technical data (device model, operating system, approximate IP-based location, and ad interactions) and processes it on Google's servers. This is a sharing of data with a third party for advertising purposes.

• 55x5 requests non-personalized ads only.
• It Works may request personalized ads where permitted; on iOS this happens only if you allow tracking when prompted.

You can reset or limit your Advertising ID in your device settings (Android: Settings → Privacy → Ads; iOS: Settings → Privacy & Security → Tracking and Apple Advertising). The other seven apps contain no advertising SDKs.

Information We Do Not Collect

• Your name, email address, phone number, or any contact information
• The content of your intentions, journal entries, affirmations, or scripting
• Precise or GPS location — analytics providers may infer only an approximate region from your IP address
• Your contacts
• Photos or camera, beyond images you personally attach inside an app (for example a vision board or evidence photo), which are stored only on your device
• Microphone audio — except in Lullaby Method, Tesla 369, and Declare, which record your own voice locally on-device; those recordings are never transmitted anywhere

Third-Party Services

The apps use the following third-party services, each with its own privacy policy:

• PostHog — product analytics and crash / diagnostic logging. Privacy Policy
• RevenueCat — subscription and in-app purchase validation. Privacy Policy
• Expo — over-the-air app update delivery. Privacy Policy
• Google (Firebase Cloud Messaging, and AdMob in It Works and 55x5) — push message delivery on Android, and advertising in the two ad-supported apps. Privacy Policy
• Apple App Store / Google Play — app distribution and payment processing, subject to Apple's and Google's respective privacy policies.

Per-App Notes

• Lumios — lets you attach photos to a vision board; images are stored only on your device.
• It Works - Manifest List — ad-supported through Google AdMob (see Advertising above); lets you attach photos to list items, stored only on your device.
• Wish Fulfilled — no data collection beyond the common set described above.
• 55x5 - Manifestation Ritual — ad-supported through Google AdMob, non-personalized ads only (see Advertising above).
• Shadow Forge — shadow work responses, body check-ins, and gratitude notes are stored only on your device and are not accessible to the developer. Intended for users aged 18 and older.
• Tesla 369 — can record your own voice for affirmations, and stores an optional birth date you enter for numerology; both stay on your device.
• Lullaby Method — records your own voice for sleep sessions; recordings stay on your device.
• Heart Coherence — with your permission, reads heart rate and heart rate variability from Apple Health or Health Connect (see Health Data below).
• Revision Method: SP Manifest — lets you attach photos to Vault entries; images are stored only on your device.
• Declare — can optionally record your own voice reading your declaration; the recording stays on your device. No financial accounts, bank connections, or real money transactions of any kind - the amount and goal you enter are never transmitted anywhere. Intended for users aged 17 and older.

Data Storage and Retention

All user-generated content (intentions, journal entries, streaks, recordings, attached photos, settings) is stored locally on your device using on-device storage. It is not transmitted to any server and is deleted when you uninstall the app.

Shadow Forge journal entries — all shadow work session responses, body check-ins, and gratitude notes are stored exclusively on your device and are never transmitted to any server or third party. This data is not accessible to the developer.

Analytics and diagnostic data held by PostHog is retained for up to 12 months and then deleted or anonymized. RevenueCat retains purchase records for the life of your subscription plus any period required by the app stores and by applicable tax and accounting law. You can ask us to delete analytics data associated with your installation by emailing the address in the Contact section.

Health Data (Heart Coherence)

With your explicit permission, Heart Coherence reads heart rate and heart rate variability data from Apple HealthKit (iOS) or Health Connect (Android) to show you how your heart responded to breathing sessions. This data is processed entirely on your device, is never uploaded to any server, is never shared with third parties, and is never used for advertising. You can revoke access at any time in your device's health settings, and the app remains fully functional without it.

Where Your Data Is Processed

Our service providers (PostHog, RevenueCat, Expo, and Google) are based in the United States and may process the data described above there. Where you are located in the European Union or the United Kingdom, this transfer relies on the providers' standard contractual clauses.

Your Rights

You can request access to, correction of, or deletion of any personal data associated with your app installation by contacting us at the address below. Because we do not collect personally identifiable information, there is usually little or nothing to retrieve, but any analytics data tied to your installation identifier can be deleted on request.

For users in the European Union and United Kingdom (GDPR): we rely on legitimate interest (operating, securing, and improving the apps) as the legal basis for analytics and diagnostics, and on performance of a contract for purchase validation.

We do not sell your personal data, and we do not share it for cross-context behavioral advertising, other than the Advertising ID sharing described above for It Works and 55x5.

Uninstalling an app deletes all data stored on your device by that app.

Children's Privacy

These apps are not directed at children under the age of 13, and Shadow Forge is intended only for users aged 18 and older and Declare only for users aged 17 and older. We do not knowingly collect personal information from children.

Changes to This Policy

We may update this Privacy Policy from time to time. The "Last updated" date at the top of this page reflects the most recent revision. Continued use of the apps after any changes constitutes acceptance of the updated policy.

Mental Health Disclaimer

Shadow Forge is a self-guided journaling tool designed to support personal reflection based on Jungian psychological concepts. It is not a medical device, clinical service, psychotherapy, or substitute for professional mental health treatment.

The app does not provide diagnoses, clinical assessments, or therapeutic interventions. Content is for informational and self-reflective purposes only.

Shadow work and introspective journaling may surface strong emotions. Users should exercise personal judgment about their readiness to engage with this type of content. If you experience distress, suicidal thoughts, or a mental health crisis, please immediately contact a licensed mental health professional or a crisis service in your country.
