90 Seconds: Why We Delete Files Faster Than Anyone

The number 90 is not arbitrary. It represents the maximum time your file exists on our servers: 90 seconds from upload to permanent deletion. This article explains the engineering and philosophy behind that decision.

Why 90 Seconds?

We needed a window long enough to handle large file conversions, but short enough to meaningfully protect privacy. Here is how we arrived at 90 seconds:

• 0-5 seconds: File upload time for a typical 5-25MB file
• 5-60 seconds: Conversion processing time (format-dependent)
• 60-90 seconds: Download window for the user

Ninety seconds gives you enough time to upload, convert, and download without rushing, while ensuring your file does not linger on our server. After 90 seconds, both your original file and the converted output are permanently deleted using secure filesystem operations.

How the Deletion Works

Our deletion process is not a soft delete or a database flag. It is a hard, permanent filesystem deletion:

1. The file path is identified in our temporary storage.
2. The filesystem inode is unlinked, making the data immediately inaccessible.
3. The disk blocks previously holding the file are marked as free space.
4. A cleanup thread verifies deletion and removes any associated metadata.

Once deleted, the file cannot be recovered by anyone, including our own team. There is no backup, no archive, no recovery mechanism. This is by design.

The Countdown Timer: Transparency by Default

When you upload a file to ModiFile, you see a visible countdown timer showing exactly when your file will be deleted. This is not a gimmick. It is accountability. If we claim to delete files in 90 seconds, you should be able to verify it yourself.

The timer starts the moment your file finishes uploading and counts down in real time. When it reaches zero, the file is gone. No exceptions, no extensions, no grace periods.

Comparing Deletion Policies

Here is how ModiFile compares to other popular file converters:

Service Type	Typical Retention	Risk Level
Mainstream converters	24 hours to 30 days	High
Premium converters	1-7 days	Medium
Privacy-focused	1-24 hours	Low
ModiFile	90 seconds	Minimal

What About Server Backups?

A common question is whether server backups might retain copies of deleted files. The answer is no. ModiFile processes files in a temporary directory that is explicitly excluded from all backup systems. Even if someone gained access to our server backups, there would be no user files to find.

The Philosophy: Privacy as Architecture

Most privacy policies are legal documents that explain what data a service collects and how they use it. ModiFile does not need a complex privacy policy because we collect nothing. Our privacy protection is not a policy, it is an architecture.

We cannot violate your privacy because we engineered the system so that your data does not persist long enough to be violated. Ninety seconds is not just a feature. It is the foundation of everything we built.
