My go-to cloud? Proton Drive.

I use it daily to store my configs, reports, and sensitive notes 🤫

Real Zero-Knowledge: Even if Proton gets pwned or receives a subpoena, my files remain unreadable. It's the only way to sleep soundly.

Available on Android, iOS, and macOS. And for colleagues still stubbornly on Windows: yes, it works there too. No compromises.

🇨🇭 It's Swiss, ad-free, no tracking, and my data is never used to train AI models.

I truly believe this is a solid, repeatedly audited solution. Stop trusting your data to giants who monetize it.

Small E2EE sharing demo from Reborn Apps - zero-knowledge, demonstrated by using the feature on itself.

What you're opening: the design doc that explains how shared snapshots work, served as a password-protected snapshot from a real account.

Shared note - re/notes

End-to-end encrypted snapshot of a note shared with you.

re/task & re/notes just got a unified search box with 10+ operators.

Examples:
due:<7d -is:completed → open, due this week
list:Inbox is:starred → starred in Inbox
tag:reading has:link → tagged notes with a link

…also folder:, created:, modified:, is:overdue and more.

Plus boolean OR / AND / parentheses. Runs client-side - server never sees your query.

🔐 Strong passwords matter — but for teams, they’re not enough.

On World Password Day, we’re looking beyond password rules and at what really matters for secure collaboration: identity-based access, clear permissions, and zero-knowledge encryption.

Self-hosting. One of the core benefits of open-source software is the ability to run it yourself: https://reapps.eu/blog/self-hosting-with-docker-compose/

Why self-host?
For most users, our public instance (https://reapps.eu) is the easiest way to get started -it’s free, always up to date, and supported by the community. Self-hosting is an option for individuals and organizations with specific requirements.

Приватные платежи на блокчейне Polygon: как ZK-доказательства стыкуются с регулятором

Приватные стейблкоин-платежи на Polygon: как ZK-доказательства стыкуются с регулятором 4 мая 2026 Polygon Labs объявил, что в Polygon Wallet добавлен пункт «Приватная отправка» (Privately Send) — отправка USDC и USDT с сокрытием отправителя, получателя и суммы транзакции. Технологический партнёр — Hinkal, протокол шифрованных пулов с верификацией через протокол доказательств с нулевым разглашением. Разбираемся, где слабые места в модели и почему этот паттерн важен далеко за пределами платежей — для RFQ-протоколов и опционов

Why we need more Zero-knowledge tools?

[Part 2 of 2]

Zero-knowledge architecture complicates investigations, especially counter-terrorism. Agencies cannot obtain readable content from providers forcing reliance on device forensics (Cellebrite tools), metadata analysis, human intelligence, financial tracking, and international cooperation. India’s first comprehensive National Counter-Terrorism Policy, PRAHAAR (unveiled February 23, 2026 by the Ministry of Home Affairs) [3], identifies strong encryption and anonymous messaging as tools exploited by terrorists for anonymity and coordination. It calls for enhanced digital forensics, AI-driven pattern detection, platform accountability, and disruption of cyber networks. However, it does not impose a blanket ban on zero-knowledge tools.

Zero-knowledge tools are a net positive for privacy and democracy when used responsibly. They do not create perfect secrecy. As mentioned earlier, law enforcement can still use device forensics, metadata, and intelligence. Privacy does not guarantee democracy, but its absence consistently undermines it by limiting free expression and allowing abuse of power.

Zero knowledge tools need better usability for wider acceptance in India. They must support Indian languages and UPI style payments. Free tiers should be generous, with enough storage and features for daily use. Simple education campaigns are required in schools, colleges, and through regional languages. These campaigns must explain why basic end to end encryption is not enough and how zero knowledge works. Network effects can be strengthened with easy invite friends tools. India based data centres or local representatives will help faster compliance. Privacy should be marketed as protection from data theft and misuse, not just as anti government.
