Security is not the problem ? control is.

Problem

Here are the real data-security problems:

  • 🌐 Platforms can access your data.
  • 📝 Files can be copied or forged.
  • ®️ Authenticity is hard to prove.
  • 🧩 Complex security tools scare off regular users.

Solution

  • ✉️ Secure delivery over public channels.
  • 🌐 Protection from platforms and intermediaries.
  • 📝 Viewing and editing inside a protected app.
  • ®️ Proof of integrity with built-in logs.
  • 🧩 Simple intuitive app for protecting and sharing data.
  • ⚙️ Access opens only at the right time and/or place.

Find your scenario

Who uses TrueLock?

One product, three ways to monetize access control.

📈
Cappers and Traders
People do not trust your calls. They say you edit after the fact.
Lock your prediction before the event. The capsule opens after the match so everyone sees you knew first. Or sell the password in advance to paying users.
Unlock after the event OR with a purchased password
🏢
Stores, Cafes, Restaurants
The customer came once and disappeared. Ads are expensive with weak results.
Send a reward capsule after purchase. It opens only in your venue and only until week end. The customer physically returns - no ad budget needed.
Only at the geo point AND before expiry date
⚡
Flash Sales and Drops
You launch a promo and nobody reacts. Users see hundreds every day.
Send the capsule in advance to all your audience. The offer appears at 18:00 and disappears at 18:05. People wait with timers. Hype without ad spend.
Only from 18:00 TO 18:05, then closed

🔓
Capsule opened
After the match everyone sees the prediction. Creation date is inside the capsule. Proof is undeniable.

💰
Reputation and revenue
Fairness is proven publicly. The next signal pack sells at a higher price.

Essential answers

Frequently asked questions

This section is written in plain language for users, search engines, and AI assistants.

What is TrueLock?

TrueLock is an app for protecting files and messages as encrypted capsules. A capsule opens only when the right access conditions are met.

Which access conditions are supported?

TrueLock supports time-based unlock, geo-based unlock, password protection, visual-key unlock, and AND/OR combinations of these rules.

How is TrueLock different from a normal encrypted file?

Normal encrypted files protect content at rest. TrueLock adds control after sending by attaching unlock rules to the encrypted capsule itself.

Which platforms are available?

TrueLock currently supports Android and Windows. The same capsule format is designed to be portable across supported devices.

Do recipients need an account or paid plan?

No. The complete application is free forever for creating, opening, and verifying capsules.

Does TrueLock require a cloud service?

No. TrueLock is offline-first. You can create a capsule and send it through your existing channels without a mandatory TrueLock cloud account.
