Chained — tzastin

Chained is a minimal, privacy-first accountability website blocker built for deep focus and mutual commitment.

Instead of relying solely on willpower, bind your focus pact to an accountability partner using a simple 6-digit invite code. Once chained, your distracting websites are locked away until your session concludes.

• Mutual Accountability Pacts: Connect with a friend, coworker, or study partner in seconds with an invite code. Both browsers enter locked focus mode simultaneously.
• 100% Zero-Knowledge Privacy: Your blocked website list never leaves your device. Neither the relay server nor your partner ever sees which websites you block.
• Flexible Restriction Schedules: Choose how restrictions apply:
• Always Active (24/7)
• Daily Work Hours (e.g. 9:00 AM - 5:00 PM Mon-Fri)
• Active Focus Timer (lock in for 1, 2, or 4 hours)
• Partner-Approved Inactive Breaks: Need a temporary break for lunch or research? Request a 15, 30, or 60-minute reprieve. Restrictions only pause if your partner approves, complete with a live countdown timer.
• Dynamic Vault Modifications: Propose adding or removing sites during an active pact. Changes require your partner's mutual approval.
• The Mark of Shame: If either partner surrenders and uninstalls the extension, the other partner is immediately notified and the incident is logged in their History.
• Honorable Mutual Unchain: When you are done, both partners can agree to end the session peacefully without shame.
• Minimal Interface: Dark mode, glassmorphism, micro-animations, and clean typography designed to look sleek and modern.

Chained is designed with zero-knowledge principles from the ground up:
- No tracking, analytics, or advertising scripts.
- No accounts, passwords, or personal data required.
- All domain blocking is performed locally within Firefox.
