Independent app & game studio
Erebos Lab
We design, build, and ship real products — live web apps, App Store mobile apps, and games — then host every one's privacy, terms, support, and account-deletion pages here, on a single umbrella domain.
An independent studio building across the stack. Our flagship products run live on their own domains; every mobile app and game we ship is hosted here with its App Store / Google Play compliance pages — so we stop buying a domain per app.

Frequently asked questions
What is Erebos Lab?
Erebos Lab is an independent app and game studio. We build web products on their own domains and ship mobile apps and games — and we host every app's App Store and Google Play compliance pages (privacy policy, terms, support, and account deletion) here on one domain.
Are the apps free to download?
Yes. Every app and game lists at no upfront cost, with optional in-app purchases or subscriptions handled by the App Store or Google Play. Many titles are fully usable for free.
Do Erebos Lab apps track me or sell my data?
No app sells your personal information. Many of our apps are local-first and store your data only on your device. Each app publishes an honest, per-app privacy policy with an Apple and Google data-safety summary that matches exactly what the app collects.
How do I get support, cancel a subscription, or delete my account?
Every app has its own Support and Delete-account page linked from its overview, and you can email [email protected] directly. Subscriptions are managed in your App Store or Google Play account settings.
