Privacy Policy

Who we are

Enzuna is a personal relationship notebook app operated by the Enzuna team. For privacy questions or requests about data you have sent us, contact enzunateam@gmail.com.

Summary

Your contact and relationship notebook stays on your device. Enzuna has no account and no ads. We do not sell your data. Separate optional features may send data over the internet: anonymous usage statistics (on by default, with an in-app opt-out), automatic crash reports in production builds, feedback you choose to send, and place-search queries when you use location pickers.

Contact access

With your permission, Enzuna reads your phone contacts so you can build and sync your personal relationship notebook. Enzuna may update a phone contact only when you edit contact fields inside the app. Names, phone numbers, emails, birthdays, work details, and related contact fields used by the notebook are stored locally on your device and are not uploaded by the core notebook features.

Relationship notebook

Notes, family members, preferences, follow-ups, life events, and other relationship details you enter are stored in a local database on your device. This content is not transmitted to Enzuna servers as part of normal notebook use.

Reminders

Birthday, check-in, and follow-up reminders are scheduled on your device using local notifications. Reminder content and timing are not sent to Enzuna servers.

Anonymous usage statistics

In preview and production app builds, Enzuna collects anonymous usage statistics to understand how the app is used and to improve it. Analytics are on by default and can be turned off at any time in Settings → Share anonymous usage statistics.

When enabled, we may collect:

• Event names (for example screen views, onboarding steps, feature usage counts)
• Screen or route names
• App version and platform (Android or iOS)
• Device model and coarse device metadata supplied by the analytics SDK
• Session and timing metadata needed for product analytics

We do not include contact names, notes, relationship content, or place-search queries in these events. Analytics are processed by PostHog on EU-hosted infrastructure (eu.i.posthog.com). PostHog assigns an anonymous identifier to your app installation; it is not linked to your identity or contact notebook. Event data is retained according to our PostHog project settings (typically up to several years unless deleted earlier).

Crash reporting

Preview and production builds automatically send crash reports to Sentry when the app crashes. Reports may include stack traces, device state at the time of the crash, app version, and platform. They are used only to diagnose and fix defects. Crash data is retained according to our Sentry project settings (typically around 90 days unless configured otherwise). There is no in-app toggle for crash reporting; local development builds do not send crash reports.

Feedback

If you choose to send feedback from Settings, the following may be transmitted over HTTPS to our Supabase Edge Function and then delivered by email through Resend:

• Your feedback message
• An optional reply email address you provide
• Optional images or screenshots you attach
• A random device identifier generated for feedback (not your contact data)
• App version and platform

To prevent abuse, we combine the feedback device identifier with your network IP address to create a hashed rate-limit key stored in our Supabase database. Rate-limit records track submission counts within rolling one-hour windows. Feedback emails and attachments are retained in our support mailbox until we delete them. To request access, correction, or deletion of feedback you sent, email enzunateam@gmail.com.

Place search

When you use a location picker and type a place name, your search query is sent over HTTPS to the public Photon geocoding service (operated by Komoot) to show suggestions. Normal network metadata (such as IP address) may be processed by that service. Place queries are not included in anonymous usage statistics events.

Security

Data transmitted off your device is sent over encrypted HTTPS connections. Your local notebook is stored in the app's on-device database protected by your device operating system.

Advertising and sale of data

Enzuna shows no advertisements and does not sell personal information. Anonymous usage statistics and crash reports are used only to operate and improve the app.

Your choices

• Turn anonymous usage statistics off or on in Settings at any time.
• Choose whether to send feedback or use online place search.
• Revoke contacts or notification permissions in your device settings.
• Erase local Enzuna data by uninstalling the app or clearing app data in your device settings.
• Contact us to request deletion of feedback you previously sent.

Children

Enzuna is intended for adults managing personal relationships. It is not directed at children under 13 (or the applicable age in your region), and we do not knowingly collect personal information from children.

International processing

Enzuna is operated from the European Union context where applicable. Service providers may process data in the EU or other countries according to their own terms and safeguards. PostHog analytics for Enzuna use EU hosting.

Changes

We may update this policy when the app or our providers change. We will revise the effective date at the top of this page. Material changes may also be noted in app release notes or on enzuna.app.
