Frequently Asked Questions
What is a virtual data room?
A virtual data room is a secure online space where you store and share confidential documents with people you choose. Instead of emailing PDFs or using a shared drive, you control who sees what, when access expires, and who downloaded or viewed each file. Common uses: fundraising, M&A due diligence, investor updates, and board materials.
Why would I use Sendpaper instead of DocSend, Papermark, Dropbox, or Google Drive?
Those tools are great for everyday files. Sendpaper is built for high-stakes deals. Like Papermark we are open source, but we add full data rooms, compliance, and multi-region. You get per-link, per-folder, and per-document permissions with granular view and download toggles, view-only mode, watermarking, and a full audit trail. When an investor opens your deck, you see it. When a buyer asks for more docs, you can stage access. No guessing who read what.
How do I set up a data room?
Sign up, create a data room, and either start from scratch or pick a template (fundraising, M&A, IPO, board portal). Add folders, upload documents, create links with your preferred settings (password, expiry, watermark), and invite viewers. Most teams have a room ready in under an hour.
What can I actually use this for?
Fundraising rounds, investor updates, M&A due diligence, board meetings, LP reporting, legal case files, and any process where you share sensitive docs and need to know who saw what. Many teams start with a single tracked link for a pitch deck, then grow into a full room as the deal heats up.
Can I use my own domain and branding?
Yes. You can add your logo, colors, and a custom domain so shared links look like they come from your company, not ours. Branding applies per data room or across your organization, depending on your plan.
Can I self-host Sendpaper?
Sendpaper is open source. Self-hosting is an option for teams with strict data residency or security requirements. Reach out to discuss your setup.
How secure is it?
Documents are encrypted at rest (AES-256) and in transit (TLS). You control access with passwords, expiry dates, view-only mode, watermarks, and IP or domain allowlists. Every view and download is logged. You can revoke access anytime.
Can I control who accesses what?
Yes. Set view and download permissions per link, per folder, and per document. Use groups for different parties (e.g., investors vs. advisors). Granular view and download toggles per item mean some links see and download everything; others get only what you release. You decide.
How do you prevent someone from sharing my docs?
View-only links mean viewers can't download. Watermarking ties content to the viewer. Audit logs show who accessed what and when. If someone misuses a link, you revoke it. We also support allowlists so only specific domains or IPs can open links.
Where is my data stored?
In secure cloud infrastructure in regions like the US and EU. Multi-region options are available so you can keep data close to your team and stakeholders. Ask us about your region.
Do you comply with GDPR and CCPA?
We're built with privacy in mind and offer data residency choices. If you need specific compliance guarantees (e.g., DPA, BAA), contact us and we'll walk through what we can provide.
Can I use this for HIPAA-covered healthcare data?
Sendpaper is built for deals and confidential documents, not as a HIPAA-ready platform out of the box. Healthcare use often needs extra safeguards. Reach out and we can discuss your requirements and options.
