Hey Product Hunt! 👋 I'm Joseph, a solo founder and business school student from France. I built Airlock because I kept seeing professionals — especially lawyers — sharing sensitive client files through email attachments or generic cloud links with zero control over who sees what. The problem is simple: once you send a file, you lose all control. No way to know if it was forwarded, downloaded 50 times, or still floating around months later. Airlock fixes that: 🔒 Password-protected sharing links 📊 View & download quotas — set exactly how many times a file can be opened ⚡ Instant link revocation 📝 Optional PDF watermarking 👁️ Full access logs — who, when, from where 🔐 Read-only document viewing (no download option) Everything is encrypted (AES-256) and the server runs in France. Free plan to try it out, Pro at €12/month — no tricks, no enterprise-only pricing wall. I'm a one-person team, so I read every piece of feedback personally. Would love to hear what you think — especially if you handle confidential documents in your work. What's missing? What would make you switch from your current setup? Thanks for checking it out! 🙏
