**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?

The Team plan includes 1 data room and the Data Rooms plan is unlimited. Data rooms aren't on Free or Pro. 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.
