Your Data Stays Yours — Guaranteed

ExcelaDoc is built from the ground up as a multi-tenant SaaS platform. Every database query, every API call, every piece of data is automatically scoped to your organization ID.

  • Ironclad data vaults—your information never mixes with other customers
  • Multiple security layers protect your competitive intelligence
  • Even our engineers can't accidentally expose your data to others
  • Your proposals remain exclusively yours, guaranteed

Why this matters: Your competitor using ExcelaDoc can't see your proposals, win rates, or content library. Your data is logically and physically separated at every layer.

Independent Security Vaults

Your proposals are in your vault.
Your past performance records are in your vault.
Your competitive intelligence is in your vault.

No other customer can see your data, even if they tried.

Your Data Is Never Used to Train AI Models

ExcelaDoc does not, and will not, use your proposal data, RFP responses, past performance records, or any other Customer Data to train, fine-tune, re-train, benchmark, or improve any artificial intelligence or machine learning model — including our own and those of any third-party provider.

This is not an opt-out. There is no toggle, no tier, and no exception. It applies to every customer on every plan, permanently.

  • Your win strategies never leave your vault
  • Your pricing models are never exposed to AI training pipelines
  • Your past performance data remains exclusively yours
  • Committed in both our Terms of Service and Privacy Policy

Zero AI Training on Your Data

No opt-out needed — your data is never in the training pipeline to begin with.

Contractually committed in our Terms of Service & Privacy Policy.
