**Plox Tip:** Looking for a specific feature? Use the sidebar — every question here links to the deep-dive doc.

## Account & billing

### Is there a free plan?

Yes. The Free plan covers one organization, fifty documents, and three links — enough to try every core feature before upgrading.

### Can I change my plan later?

Anytime. We prorate the difference automatically when you upgrade and let you downgrade at the end of your billing cycle.

### What's the cancellation policy?

Cancel any time. You keep access until the end of the period and on annual plans we refund the unused time.

## Documents

### What file types are supported?

PDF, PPTX, DOCX, XLSX, JPG, PNG, MP4, and most common office formats. See [Uploading a document](/docs/uploading-a-document) for the full list.

### What's the upload size limit?

Limits scale with your plan — see [Upload limits](/docs/upload-limits) for current numbers.

### Can I update a file after sharing?

Yes. Replace the file and the same link automatically serves the new version. Viewers always see the latest revision the moment they reopen the link — no need to re-share.

### Can I revoke a link?

Yes, instantly, from the document row. Active viewer sessions are kicked on their next page load.

## Data rooms

### When should I use a Data Room instead of a Document?

Use a Data Room when you're sharing more than one file with the same audience, or when the experience matters (fundraising decks, due diligence, M&A). Otherwise, a Document is faster to set up. See [What is a data room](/docs/what-is-a-data-room) for the full guide.

### How many Data Rooms can I have?

Plus = 1, Pro = 3, Max = unlimited. See [Pricing](/pricing).

### What is Plox AI?

AI that turns your pitch deck into a dashboard of metrics and summaries inside your data room. See [Plox AI](/docs/plox-ai).

## Security

### Where is my data stored?

In SOC 2 Type II compliant data centers, encrypted at rest with AES-256.

### Can viewers download my file?

Only if you allow it. See [Disabling downloads](/docs/disabling-downloads-for-shared-files).

### Can viewers screenshot?

Mobile screenshots are blocked. Desktop screenshots carry the dynamic watermark, so leaks are traceable to the specific viewer.

## Analytics

### When do I get notified of a view?

In real time — both an email alert and a live entry in your **Analytics** tab. See [What events trigger alerts](/docs/what-events-trigger-alerts).

### What does "completion rate" mean?

The percentage of the document a viewer scrolled through in a single session. A drop-off mid-document is one of the strongest engagement signals you can read — see [Tracking your document](/docs/tracking-your-document) for what to do about it.
