About Jolly Good Apps

Apps, games, and browser extensions that respect your time and privacy.

Privacy-Focused Apps, Games & Extensions

We build phone apps, games, and browser extensions designed to respect your data. Our tools use minimal permissions and local-first storage — no harvesting, no first-party tracking, no nonsense.

The principles behind everything we make:

  • Minimal permissions - We only request the access a tool genuinely needs to do its job
  • Local-first storage - Your data stays on your device. Our extensions use Chrome's sync storage only when you choose to sync across devices, and our apps and games keep your progress and settings on your device
  • No first-party tracking - We don't monitor your browsing, track the sites you visit, or build advertising profiles about you, and any usage analytics we collect to improve our tools are anonymous and aggregate
  • Ad-supported games, clearly disclosed - Our free games are funded by ads served through Google AdMob, which uses your device's advertising identifier to show and measure them. That advertising data is handled by Google, kept separate from anything we collect, and you can reset or limit it in your device settings. Our browser extensions and Artsplainer are ad-free
  • Honest pricing - Free tiers that are genuinely useful, not crippled demos designed to force upgrades

Every app, game, and extension has its own privacy policy setting out exactly what it does and doesn't collect — you'll find it on each product's page or app-store listing.

  • Timestamp Bookmarks for YouTube - Save multiple timestamps per video with personal labels. Never lose your place in long videos, lectures, or tutorials.

Why Choose Privacy-First Tools?

Many popular apps, games, 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 each product's privacy policy clearly explains what we do (and don't) collect.
