Zero Data Retention (ZDR)

Your data is processed. Never stored.

What is Zero Data Retention?

Zero data retention (ZDR) is a data-handling policy under which a service provider processes data only for the immediate purpose of fulfilling a request and does not store, log, or retain that data after the interaction is complete. The term was popularized by AI companies like OpenAI and Anthropic, who offer ZDR agreements to enterprise customers who need assurance that their data won't be used to train foundation models.

But the principle doesn't stop at AI. Any SaaS tool that touches sensitive data, spreadsheets included, should be held to the same standard. Row Zero extends zero data retention to the entire analytics workflow: every query, every calculation, every cell.

For Row Zero customers, this means:

No persistent storage of spreadsheet content or analysis outputs beyond your active session.
No use of customer data to train, fine-tune, or improve AI or machine learning models.
No third-party subprocessors involved.

For organizations subject to strict regulations like GDPR, HIPAA, SOC 2, or CCPA — or internal data governance policies — zero data retention is not optional. It is a foundational requirement for any tool that processes sensitive financial, operational, or customer data.

Why Zero Data Retention matters for cloud data analysis

Traditional spreadsheet tools were never designed with cloud-scale data governance in mind. When teams export data into Excel files or Google Sheets, they create uncontrolled copies that leave the governed environment landing on laptops, email inboxes, personal drives, and third-party cloud services. Each copy represents a new breach surface, a new compliance obligation, and a new governance headache.

Modern SaaS analytics tools introduce a different risk: data is routinely retained by the vendor for logging, debugging, model training, or product analytics. Even tools marketed as 'AI-powered' frequently store query history, user inputs, and output data in ways that violate enterprise data policies.

The risks of data retention in traditional tools

Data sprawl: Exported CSVs and Excel files proliferate across devices and cloud storage, creating untracked copies of sensitive data.
Breach exposure: Every retained copy of sensitive data is a potential breach vector and a potential regulatory fine.
AI training risk: Many AI-powered tools retain user inputs to improve their models, meaning your proprietary analysis and sensitive data may be used to train models accessible to other customers.
Compliance burden: Data retained by vendors complicates GDPR right-to-erasure requests, HIPAA audit trails, and SOC 2 evidence collection.
Governance gaps: Data that leaves your warehouse loses the row-level security, RBAC, and audit controls you have invested in building.

Row Zero eliminates these risks by design. Data is queried directly from your warehouse, processed in memory, displayed in the spreadsheet, and discarded when the session ends without ever being written to persistent Row Zero storage.

Zero Data Retention Architecture

The Row Zero architecture is designed so that your data never needs to be stored by us to deliver a fast, powerful spreadsheet experience. Here is how we enforce zero data retention at every layer of the product:

Real-time, in-memory processing

When you connect Row Zero to a Snowflake, Databricks, Redshift, BigQuery, Postgres, Amazon S3, or Oracle data warehouse your queries are executed directly against your warehouse and results are streamed into your active spreadsheet session. Data is held in memory for your session only. It is not written to Row Zero databases, object storage, or logs.

All workbook data is persisted in your cloud storage account

Row Zero does not write spreadsheet content, query inputs, or analysis outputs to any persistent storage layer. This applies to:

Spreadsheet cell contents and formulas
Data warehouse query text and results
Python code and execution outputs
AI assistant prompts and responses
Pivot table configurations and chart data

No training on your data

Your prompts, your data, and your outputs are never used to train or fine-tune AI models by Row Zero or by our AI model providers. Enterprise customers who bring their own API key (BYOK) have direct control over their AI provider's data policies.

Governed access data never leaves the cloud

Because Row Zero connects directly to your data warehouse rather than exporting data to local files, sensitive data never travels to employee laptops, personal cloud accounts, or unmanaged devices. Administrators can enforce export controls, clipboard restrictions, and download policies to ensure data stays within the governed cloud environment.

Row Zero Private Storage is an enterprise security feature in Row Zero is often referred to as "Bring Your Own Object Storage." It is designed to satisfy strict compliance and data governance requirements for organizations handling large, sensitive datasets

Minimal operational logging

Row Zero retains only the metadata necessary to deliver, secure, and improve the service such as authentication events, access logs for security auditing, and session metadata. Sensitive data content is explicitly excluded from all operational logging pipelines.
