Radical Transparency & Privacy
In an era of subscription fatigue, intrusive data tracking, and surprise paywalls, being 100% free naturally makes people suspicious. Here is our honest, technical explanation.
Unlike traditional apps that maintain expensive cloud databases for every customer, 123 ToDo runs 100% locally on your device using browser IndexedDB and Web Workers. Our app code is delivered via Cloudflare edge servers, meaning hosting costs for 100,000 users are virtually identical to 10 users.
You don't need to trust our servers with your personal life or business tasks. All data is encrypted directly on your device with military-grade AES-256-GCM before any cross-device sync occurs. Neither we, Cloudflare, nor Google possess your encryption keys, so no one can view, monetize, or scan your data.
We are self-funded and completely open source under the permissive MIT License. Anyone can inspect and audit our complete client-side codebase on GitHub to verify our zero-knowledge security. No venture capitalists, no ads, no trackers, and no paywalls.
You can export your complete workspace to open standard JSON anytime with 1 click, or sync directly to your personal Google Drive.
