Privacy-first data visualization

Your data never leaves. Your charts go everywhere.

Most chart tools need your data on their servers before they can draw anything. Datastripes does not. The whole engine, from parsing to statistics to rendering, runs inside your browser in WebAssembly, so you can visualize confidential data and publish only what you decide to publish.

No card. No install. Drop a spreadsheet and you are already writing.

Everything you see below was computed and drawn in your browser. Open your network tab: no data rows are sent anywhere.

Same data, same file, two ways to read it. Sample data, built for this page.

How the privacy model works

  1. 01

    Load locally

    Your file is read by the browser. It is parsed and stored in memory on your device.

  2. 02

    Compute locally

    Filters, aggregations, statistics and forecasts run in WebAssembly on your CPU.

  3. 03

    AI sees the shape, not the rows

    The assistant receives column names, types and summary stats, never the records.

  4. 04

    Publish only aggregates

    When you embed, you choose exactly what is shared: the chart and the numbers it shows.

Why client-side is different

With a traditional SaaS chart tool, “privacy” is a policy: the vendor promises to protect the data it holds. With Datastripes it is architecture: on private plans we do not hold the rows in the first place. Data you never upload cannot be breached, subpoenaed from us or used for training.

This also makes the tool fast. There is no upload queue or server round trip, and filtering half a million rows happens at the speed of your laptop.

What is shared when you publish

Publishing creates a chart that other people can see, so something must be shared. Datastripes shares only what the chart needs: typically aggregated values, not the raw file. You can preview the exact published dataset before you click Publish, and password-protect it on Pro. Free public projects are published to the gallery, so use a private plan for sensitive data.

GDPR, HIPAA-style constraints and data residency

Because raw records stay on the user’s device, many projects never involve Datastripes as a processor of personal data at all, which simplifies records of processing and DPIAs. Enterprise customers get a DPA, SSO, audit logs and a self-hosted embed runtime for full data residency. Always confirm your specific use case with your data protection officer.

“The safest copy of your data is the one that was never made.”

Vincenzo Manto, founder of Datastripes

Privacy questions

Does Datastripes upload my data?

Not on private plans. Data is processed in your browser. Only the chart you publish, typically aggregated, is shared.

What does the AI assistant see?

A compressed schema: column names, types and summary statistics. Never your individual rows.

Is it GDPR compliant?

The client-side design minimises personal data processing. Enterprise includes a DPA. Check your specific use case with your DPO.

Are free projects private?

No. Free projects are public and listed in the gallery. Use Pro or above for private data.
