Frequently Asked Questions

Single use access is the cornerstone of InfoBin's security model. When content can only be accessed once, you gain complete control over your sensitive data. This prevents unauthorised sharing, eliminates the risk of links being passed around, and ensures that once your intended recipient views the content, it vanishes forever. Each share exists in complete isolation, providing perfect forward secrecy. No other file sharing service offers this level of guaranteed confidentiality.

Automatic deletion is your guarantee that sensitive content never persists beyond its intended purpose. The moment your recipient accesses the file or message, it's permanently erased from our servers. No copies, no backups, no recovery possible. This eliminates data breach risks entirely because data that doesn't exist cannot be stolen. You can also set time limits for automatic deletion if content isn't accessed, giving you complete control over your data's lifetime.

InfoBin operates on pure anonymity principles:

• No account creation required, ever
• No email addresses collected or stored
• No personal information requested at any point
• No IP address logging or tracking
• No cookies that could identify you
• Complete separation between payment processing and usage
• Access codes are anonymous bearer tokens

This isn't just privacy theatre. We literally cannot identify you, track you, or connect your activities. True anonymity means true freedom.

Absolutely not. Tracing is impossible because we never know who you are. Payment processing is handled externally by Stripe with no connection to your usage. Access codes function as anonymous bearer tokens that aren't linked to any identity. Our zero knowledge architecture means we cannot see your content, and with no user accounts or tracking, there's no way to connect any activity to any person. You have complete plausible deniability.

InfoBin employs triple layer security that makes unauthorised access virtually impossible:

• Access Code: A 64 character cryptographic token providing anonymous authentication
• Password: Your personal secret key that you create and control
• Unique URL: Contains additional cryptographic identifiers with 256 bit entropy

All three elements must be present simultaneously for access. Even if someone intercepts your link, it's useless without the password and access code. This defence in depth approach provides military grade protection.

Our long URLs contain 256 bits of entropy, making them mathematically impossible to guess or forge. While short URLs might seem convenient, they're vulnerable to brute force attacks where hackers systematically try different combinations. Our URLs would take longer than the age of the universe to crack, even with the world's most powerful computers. Think of it as having a 64 character password built into every link. This isn't a limitation, it's fortress level security.

Zero knowledge means we cannot see, access, or decrypt your content under any circumstances. Your data is encrypted before it reaches our servers using keys we never possess. Even if compelled by legal orders or threatened by hackers, we cannot reveal what we cannot see. There are no backdoors, no master keys, no exceptions. This isn't just a privacy promise, it's a mathematical guarantee built into our architecture.

Permanent deletion is a critical security feature, not a limitation. When content is deleted, it's overwritten and purged from all systems immediately. No backups, no recovery methods, no exceptions. This guarantees that your confidential information can never resurface. Even InfoBin cannot retrieve deleted content. This irreversibility is what makes InfoBin trustworthy for the most sensitive communications.

Email attachments remain on servers indefinitely, creating permanent security risks. They're stored in sent folders, recipient inboxes, backup systems, and email provider archives. InfoBin eliminates these vulnerabilities entirely. Your content exists only until accessed once, then vanishes completely. No copies linger on servers, no metadata trails remain, and you maintain complete control. Email was never designed for secure file transfer, InfoBin was built for it from the ground up.

Cloud storage services keep your files indefinitely until manually deleted, can be accessed unlimited times, and require accounts that identify you. They're designed for persistence, not security. InfoBin takes the opposite approach: one view then permanent deletion, no accounts needed, complete anonymity. Cloud services log every access, track your identity, and retain data even after you think it's deleted. With InfoBin, when content is gone, it's truly gone forever.

Specialising in documents allows us to optimise for maximum security and performance. Business documents, legal files, medical records, and confidential reports are what need the highest protection. By focusing on these critical use cases rather than casual media sharing, we can provide faster processing, stronger security, and better reliability. This isn't about limitation, it's about excellence in what matters most.

Follow these steps for maximum security:

1. Go to the Upload page and enter your access code
2. Upload your documents (up to 256MB total)
3. Set a strong, unique password
4. Receive your secure share link
5. Send the link and password to your recipient using separate channels
6. Content automatically deletes after one download

Your files are encrypted locally before upload, ensuring complete security throughout the process.

Secure messaging is simple and powerful:

1. Navigate to Send Message with your access code
2. Type your confidential message
3. Set password protection
4. Message encrypts automatically with AES 256
5. Share the link and password separately
6. Message permanently deletes after being read once

Perfect for sensitive communications that must not leave a trace.

Universal access codes are cryptographic tokens that work flexibly for either file uploads or secure messages. Each 64 character code provides military grade authentication, works exactly once to prevent reuse attacks, and maintains complete anonymity. They're not tied to any identity, making them perfect for teams who need to share codes amongst members. You decide how to use each code based on your immediate needs.

The six month validity period is a security feature that prevents old codes from becoming vulnerabilities. It encourages timely usage, provides regular security rotation, and protects against long term attack vectors. Expired codes cannot be exploited if discovered later. This time limit ensures your security posture remains strong while giving you ample time to use your purchased codes.

Absolutely. Access codes are anonymous bearer tokens that can be distributed to team members, clients, or partners as needed. There's no identity attached to codes, making them perfect for organisational use. Buy a bundle and allocate codes to different departments or projects. Each code maintains the same security guarantees regardless of who uses it.
