How it works

What actually happens
to your file.

Not a privacy policy — the plain, specific version. How long your file exists, what we never do with it, and the real limits for every tool, so you're not taking our word for it on faith.

The four steps

Upload, handled, downloaded, gone

01

You upload

Sent over an encrypted (HTTPS) connection, so it can't be read in transit.

02

It's handled

The tool does its one job — merge, OCR, redact, whatever you asked for — and nothing else touches it.

03

You download

Your result comes back to you. No account required for most tools, no email, no link to click later.

04

It's gone

Released the instant your download is ready. Not queued, not parked for an hour — zero retention.

The specifics

What we never do

Never stored.Your file isn't saved anywhere, on any plan, for any length of time.
Never queued.There's no waiting shelf — it's processed and released, not parked behind other jobs.
Never read.No person opens your file, and it's never used to train anything.
Nothing left behind.Because it's never kept, there's no retention window, no backup copy, and nothing to request a deletion of later.
Real numbers

The actual limits, per tool

Questions

Straight answers

How long is my file kept?

It isn't. Your file is handled, your result is returned, and it's released the instant your download is ready. No retention window — not an hour, not a minute.

Does anyone at PDF Cubby see my file?

No. No person opens it, and it's never used to train any model. It exists only for the seconds it takes to complete your request.

Is my file encrypted while it uploads?

Yes — the connection is secured with HTTPS end to end, so it can't be read in transit.

What's the maximum file size?

200MB for every tool except OCR, which is capped by page count (30 pages per run) instead — recognition time, not file size, is the real constraint there.

Does this apply on the free plan too?

Yes. Every word on this page is the same on Free and Pro — the only difference between plans is how many times a day you can use the advanced tools.
