# video10K PRO Mode Guide

## What PRO Mode Is

PRO mode is a separate recording flow inside the same app.

It is designed for users who want to reduce the amount of unencrypted video left on the phone during recording and encryption.

Instead of recording one large plain video and encrypting it only at the end, PRO mode works in short private segments and encrypts them as the recording continues.

## What PRO Mode Is Good For

PRO mode is meant to improve privacy in practical everyday use.

Compared with the standard mode, PRO mode is intended to increase security by reducing how long plain video exists on the device and by keeping temporary plain data more tightly contained.

It still does not provide 100 percent protection.

It is mainly designed to reduce risk against:

- ordinary people
- someone who briefly gets access to the phone
- casual browsing of files
- simple copying of phone contents

It is not honest to describe it as guaranteed protection for the most extreme secrets or against highly skilled forensic experts with enough time and resources.

## Important Warnings

- PRO mode is still beta.
- The app does not guarantee perfect security.
- The app does not guarantee perfect deletion of temporary data.
- The app does not guarantee that every phone model will behave exactly the same.
- The app creator cannot recover your encrypted files if you lose the password.
- If you forget the password, the recording may be permanently unusable.

## Very Important Password Warning

The password is the key to your encrypted file.

That means:

- the app does not store a recoverable copy of the password
- the creator of the app cannot recover it for you
- if you lose it, the file may be lost for good

Use a strong password and store it safely if you need future access.

## Can This Encryption Be Broken?

No honest app should promise an exact number of years.

What can be said honestly:

- the encryption is designed to be strong enough to resist casual attacks and ordinary users
- a strong password is much harder to break than a weak one
- weak passwords can still be guessed or brute-forced
- future hardware and future cryptanalysis may change what is considered strong

So the realistic message is:

- good protection against ordinary and low-skill access
- not a guarantee against every future or professional attack

## How PRO Mode Works

In simple terms:

1. PRO mode records in short segments.
2. Each segment is stored only in the app's private storage.
3. Each segment is checked and encrypted as quickly as possible.
4. The unencrypted segment is then removed.
5. The final result is one encrypted PRO container file.

For the user, this means you normally see one encrypted recording, not dozens of separate files.

## What Encryption Model Is Used

At a high level:

- each recording gets its own random data key
- video segments are encrypted with AES-256-GCM
- your password is used to protect that data key
- the file stores only the encrypted data and the metadata needed to decrypt it later

Practical meaning:

- without the correct password, the file should not be readable in any normal way
- with the correct password, the file can be opened inside the app
- a desktop decryptor can also be used if you have the password

## Where PRO Files Are Stored

During recording:

- temporary plain segments are stored only in the app's private no-backup storage

After recording:

- the final encrypted PRO file stays in the app's private storage

That means:

- you usually do not see it as a normal public phone folder
- it becomes visible outside the app only after export

## How To Use PRO Mode Safely

Recommended workflow:

1. Open the app.
2. Tap `PRO`.
3. Check the segment settings if needed.
4. Enter a file name.
5. Enter a strong password.
6. Start recording.
7. Stop when finished.
8. Leave the encrypted result inside the app unless you really need export.

## How To Check That Recording Worked

You can test the encrypted file inside the app:

1. Open the PRO file list.
2. Select the encrypted file.
3. Enter the password.
4. Open it in the app.

But the safest habit is:

- do not test every file unless necessary
- every decryption or playback test creates a temporary decrypted version for viewing
- the app tries to clean that data, but testing more often increases exposure

Best practice:

- test early while learning the app
- once you trust the workflow, avoid unnecessary repeated test decryptions

## Export

Encrypted PRO files can be exported out of the app.

Export means:

- only the encrypted container is exported
- not the plain recording
- the exported file can later be copied to a computer

If you decrypt a file for viewing or conversion, that creates more risk than keeping it encrypted.

## What The Desktop Decryptor Does

The desktop decryptor is a user tool.

It does not weaken the encryption by itself.

It still requires:

- the correct file
- the correct password

Without the password, publishing the decryptor does not automatically make encrypted files readable.

The real danger remains:

- weak passwords
- leaked passwords
- copied encrypted files combined with password guessing

## Safe Use Recommendations

For better privacy:

- use a separate phone if possible
- avoid a SIM card in that phone
- use airplane mode during recording and encryption
- turn off wi-fi, bluetooth, and mobile data if possible
- avoid exporting decrypted files unless truly needed
- avoid testing playback more than necessary
- use strong passwords

## Final Honest Summary

PRO mode is meant to reduce risk, not to promise perfection.

It is a practical privacy tool.

Used correctly, with a strong password, it should be much better than keeping plain video files on the phone.

But:

- it is beta
- it does not guarantee perfect deletion
- it does not guarantee protection against every professional or future attack
- it cannot help you if you lose your password
