About Jolly Good Apps

Apps and browser extensions that respect your time and privacy.

Privacy-Focused Apps & Extensions

We build privacy-first phone apps and browser extensions that respect your data. Our tools are designed with minimal permissions and local-first storage — no harvesting, no tracking, no nonsense.

Everything we build follows strict privacy principles:

  • Minimal permissions - We only request access to what's absolutely necessary for the extension to function
  • Local-first storage - Your data stays on your device. We use Chrome's sync storage only when you choose to sync across devices
  • No browsing tracking - We don't monitor your browsing activity, track what sites you visit, or build user profiles
  • Anonymous analytics only - We collect basic install/uninstall metrics and browser type to improve our extensions, but nothing personally identifiable
  • Honest pricing - Free tiers that are genuinely useful, not crippled demos designed to force upgrades

  • Timestamp Bookmarks for YouTube - Save multiple timestamps per video with custom labels, perfect for students, researchers, and anyone watching long tutorials or lectures

Why Choose Privacy-First Tools?

Many popular apps and browser extensions request broad permissions even when they don't need them, harvesting data to sell or profile users.

We believe software should request only the permissions it needs and be transparent about data collection. That's why everything we build uses local-first storage and minimal permissions, and our privacy policies clearly explain what we do (and don't) collect.
