4. Device Fingerprinting

We use browser fingerprinting technology to help prevent fraud and trial abuse. This technology creates a unique identifier based on your browser and device characteristics, including:

  • •Browser type and version
  • •Screen resolution and color depth
  • •Timezone and language settings
  • •Installed fonts and plugins

For fraud prevention: We collect device fingerprints during new subscription checkout only, under our legitimate interest in preventing fraud and abuse. This data is hashed before storage, stored on our servers and in our payment provider's order metadata, and is not used to track you across other websites. Fingerprints are not collected for credit pack purchases, subscription upgrades, or downgrades.

For analytics: If you consent to Performance cookies, we may also use fingerprinting data to improve our service and understand usage patterns.

5. IP Address and Country Detection

We collect location-related data for different purposes under different legal bases:

Country Detection for Pricing (Essential Service)

We detect your country from CDN server headers (Cloudflare, Vercel) to display prices in your local currency. This happens automatically on the server and does not require consent as it is essential for the service to function correctly. No IP address is stored for this purpose.

Trial Abuse Prevention at Subscription Checkout (Legitimate Interest)

During new subscription checkout only, we collect your IP address and device fingerprint to prevent trial abuse. This is processed under our legitimate interest in protecting our service from abuse. Both the IP address and fingerprint are hashed before storage, stored in our database until account deletion, and included in our payment provider's order metadata. This data is not collected for credit pack purchases, subscription upgrades, or downgrades.

Analytics (Consent Required)

With your consent (Performance cookies), we may also use IP-based geolocation for analytics and service improvement purposes.
