2. Overview

We build software, not surveillance.

This app does not collect personal data about your identity and does not track you across apps or services.

We collect only the minimum amount of data necessary to operate and improve the product.

3. What Data We Process

a) Usage Data

We collect limited usage data to understand how the app is used and to improve it.

This includes:

  • feature usage (e.g. actions performed)
  • timestamps
  • app version
  • operating system version
  • device type (e.g. desktop or mobile)
  • coarse geographic region (e.g. country)

This data is not used to identify you as a person.

b) Installation and Session Identifiers

When you use the app, technical identifiers are used to process usage data:

  • A random installation identifier is generated and stored on your device
  • It is unique to your installation and reused across sessions
  • It is not linked to your identity

Additionally:

  • A temporary session identifier may be used
  • It exists only for the duration of a session
  • It helps us understand how features are used within a single session

These identifiers:

  • are not combined with personal data
  • are not used for cross-app tracking
  • cannot be used to identify you as a person

c) What We Do Not Collect

We do not collect:

  • your name, email, or personal identity (unless you contact us)
  • precise location data
  • cross-app or cross-service tracking data
  • behavioral profiles

d) Analytics Infrastructure

We use our own analytics system to process usage data.

We do not use third-party analytics or tracking services.
Collected data is processed exclusively for our own purposes and is not shared with external analytics providers.

4. Payments

Payments are processed by third-party providers:

  • Lemon Squeezy
  • Stripe

We do not receive or store your payment details.

5. Legal Basis (EU/EEA)

We process usage data under:

Legitimate Interest (Art. 6(1)(f) GDPR)

Our legitimate interest is:

  • understanding how the app is used
  • improving performance and usability

We ensure that:

  • data is minimized
  • no personal identification is performed
  • no profiling takes place

6. Data Retention

We retain analytics data only as long as necessary to:

  • analyze usage trends
  • improve the product

Data may be aggregated or deleted over time.

7. Data Security

We implement appropriate technical and organizational measures to protect data against unauthorized access or misuse.
