Who We Are

"We" are Veenie, operated by Pipewriter OÜ (Sepapaja 6, Tallinn 15551, Estonia, reg. no. 14904870). And I am Ivan. I build high-fidelity physics simulations, aerospace engineering tools, and simulation-as-storytelling experiences for the space industry.

Products covered by this policy: the Veenie atmospheric simulator at veenie.space, Google Workspace add-ons including AeroSheet, and any other tools listed at veenie.space/tools.

1. Google Workspace Add-ons (AeroSheet)

This section exists specifically for Google's compliance review and for users who want to understand exactly how our Workspace integrations work.

Google API Limited Use

Veenie's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

No AI Training on Your Data

We do not use data obtained through Google Workspace APIs to train, develop, or improve any AI or machine learning models, generalized or personalized. Your spreadsheet data is yours. It does not feed the belly-of-the-beast of any LLM model or other linear-algebra-based intelligence.

What AeroSheet Actually Does

AeroSheet is a wing designer that lives in a spreadsheet sidebar. NACA profile generation, thin airfoil theory, finite wing corrections and more. All of this runs locally in your browser via the Google Sheets sidebar. When you click "Push to Sheet," our Apps Script writes aerodynamic results to your active Google Sheets spreadsheet and draws a chart. That's the full data flow.

Permissions

AeroSheet requests the minimum scopes to function:

Current spreadsheet only (https://www.googleapis.com/auth/spreadsheets.currentonly): We interact exclusively with the sheet you have open. We cannot access your other files.
Sidebar UI (https://www.googleapis.com/auth/script.container.ui): Renders the AeroSheet interface, 3D wing viewer, and controls inside the Google Sheets sidebar.
External requests (https://www.googleapis.com/auth/script.external_request): Used solely to verify your Pro license key against our validation endpoint. The app also accesses airfoil geometries from a Cloudflare data bucket, but that request is not routed via the Google Apps Script environment. Either way, no spreadsheet data is included either request: just your license key and the airfoil code.
Storage (https://www.googleapis.com/auth/script.storage): Used exclusively to store your Pro license key (so you stay logged in) and your saved cell-bindings (so the sidebar remembers which cells map to your wing inputs) locally in Google's PropertiesService.

2. Veenie Web Simulator

Flight Telemetry

When you fly at veenie.space/fly, we log flight telemetry after 30 seconds of flight time. This includes altitude, velocity, ballast state, gas levels, battery percentage, and subsystem states.

Why: The long-term goal of Veenie is to train autonomous AI pilots for Venus atmospheric exploration. Human demonstration flights are the training data. Every flight where you survive the thermal cliff is genuinely useful science. As is the log of your ChatGPT panicking as it plummets towards the 92 bar hellscape.

This telemetry is anonymized by default. We don't attach it to your identity unless you explicitly log in or request an email copy of your flight. You can see saved flight telemetry at veenie.space/arena.

Saving Your Flight

From the flight interface, you can choose to save your telemetry and have it sent to your email. This is a transactional email: your flight log, nothing else. At the point of saving, you can optionally subscribe to the Veenie newsletter. Subscribing is never required to receive your flight data.

You can subscribe to Veenie updates via signup forms across the site or at veenie.space/subscribe. We use email to send:

Transactional emails: flight logs, license keys, purchase confirmations
Newsletter: new simulations, physics engine updates, aerospace research we find interesting

You can unsubscribe from the newsletter at any time via the link in any email or at veenie.space/unsubscribe. Unsubscribing from marketing email does not affect transactional emails related to purchases or flight saves.

We store your email address to manage your subscription and, if applicable, validate your software license. We don't sell it, we don't share it with advertisers, and we don't send you anything we wouldn't want to receive ourselves.

4. Purchases and Licensing

If you purchase a lifetime license for AeroSheet or other tools via Gumroad, Stripe handles payment processing. We store your license key, purchase date, and email address to validate your software access. We never see your payment card details.

The open-source Veenie physics engine and Venus aerostat design playground is available at github.com/hackiku/veenie. Using the open-source code requires no account and no data exchange with us.

The open-source aerodynamics engine powering AeroSheet is available separately as @veenie/aero on npm and GitHub under the MIT license. Using it requires no account and no data exchange with us.

5. NRE and Enterprise Clients

For custom simulation work: your mission specs, thruster configurations, and flight profiles stay in your infrastructure. We provide the physics engine and architecture; we don't need your sensitive data to do that job.

For ITAR-sensitive deployments, we support air-gapped and on-premises builds where zero telemetry or configuration data touches Veenie servers. See veenie.space/docs for architecture details.

6. Analytics and Technical Data

We use basic analytics on veenie.space to understand which simulations are used and to catch physics engine errors. This includes page views, session duration, and error logs. We do not use advertising trackers. Analytics data is not linked to personally identifiable information.

We do not sell personal data. We share data only with infrastructure providers necessary to operate: Vercel (hosting and edge functions), Neon/TimescaleDB (flight telemetry storage), Gumroad and Stripe (payments), and Resend (transactional email).

We may disclose data if required by Estonian or applicable international law. We will push back on requests we consider unreasonable.

8. Your Rights

You can request access to, correction of, or deletion of your personal data at any time. Under GDPR you have the right to data portability and the right to restrict processing. Deleting your license record will invalidate Pro tool access.
