Privacy Policy

Last updated: 10 November 2026

This policy explains what data the Nailbiter app (iOS and Android) and the website getnailbiter.app collect, why, and what you can do about it. Nailbiter is made by UFO Studios, Nederland. Questions: info@ufostudios.nl.

The short version

• You don't need an account. We never ask for your name, email address, phone number, contacts, photos or location.
• The app creates a random, anonymous device id. It's not linked to your name or to any other app.
• We collect usage analytics (which screens and features are used) to improve the app.
• If you turn on alerts, we store a push token so we can send them. Turn alerts off and it's removed.
• We don't sell your data, we don't share it with advertisers, there are no ads, and we don't track you across other companies' apps or websites.

What we collect and why

Anonymous device id

When you first open the app it generates a random id and stores it on your device. We use it to count how many devices use the app each day (with the date, your platform and the app version), to record your game ratings (the game, your rating and your platform) so each device counts once, and to link your alert settings to your device.

Usage analytics

The app and the website send usage events to PostHog, our analytics provider: for example which screens you open, which features you use, the app version, and your device type and operating system. Events are linked to the anonymous device id, not to you as a person. We use them to see what works and fix what doesn't. The app does not use your location. Like any website, the website's analytics receive your IP address when you visit, which can be used to estimate your country or city.

Push token and alert settings (only if you turn alerts on)

If you turn on alerts, we store your device's push token together with your alert settings: which sports and teams you want alerts for, the minimum rating, quiet hours, digest time and your time zone. We use this only to send you the alerts you chose. When you turn alerts off, the token is deleted.

Stored only on your device

Your favourite teams and sports, your spoiler-free setting and your own vote on each game are kept on your device. Deleting the app deletes them.

What we don't do

• No selling of data, and no sharing with data brokers or advertisers.
• No ads. The app doesn't show advertising and doesn't read your advertising identifier (IDFA/AAID).
• No tracking across other companies' apps or websites.

Who processes the data

We use a small number of service providers who process data on our behalf, only to run Nailbiter:

• Supabase: our database and backend (device counts, ratings, push tokens and alert settings).
• PostHog: usage analytics. PostHog stores data in the United States.
• Expo, Apple and Google: delivery of push notifications.
• Cloudflare: hosting of the website.

Some of these providers process data outside the European Economic Area, including in the United States. Where that happens, it is covered by safeguards such as the European Commission's standard contractual clauses or the EU-US Data Privacy Framework.

Legal basis

We process the anonymous device id and usage analytics on the basis of our legitimate interest in running, measuring and improving the app. We process your push token and alert settings because you asked for alerts, and you can withdraw that at any time by turning them off.

How long we keep it

We keep data only as long as we need it for the purposes above. Push tokens are deleted when you turn alerts off or when Apple or Google tell us the token no longer works. Usage analytics and daily counts are kept in anonymous form for as long as they are useful for improving the app.

Your choices and rights

• Turn alerts off in the app at any time; this deletes your push token.
• Delete the app to remove everything stored on your device.
• Under the GDPR you can ask us for access to, correction of or deletion of your data, and you can object to processing. Email info@ufostudios.nl. Because we don't know who you are, tell us your platform and roughly when you used the app so we can find the data.
• You can also complain to your data protection authority; in the Netherlands that is the Autoriteit Persoonsgegevens.

Children

Nailbiter is a general-audience sports app and is not directed at children under 13. We don't knowingly collect data from children.

Changes

If this policy changes, we'll update this page and the date at the top.
