Frequently asked questions

What does "Lifetime Deal" mean?

Pay once and get lifetime access to the Pro Plan, including all future updates. Please note that future Team/Enterprise features, or features with recurring external API costs, may be offered as separate plans or add-ons.

Where is my data stored?

All analysis data is stored and processed locally in your browser (OPFS). Your CSV data is never uploaded to external servers. Even if recipe sharing features are added in the future, only the processing steps (recipe) are shared, never the raw data itself.

What is your refund policy?

We offer a 30-day money-back guarantee, no questions asked. Please submit your request through ourcontact formwith your order ID.

What is the difference between Free and paid plans?

The Free plan limits exports to 500 rows, and recipe/preset saves to 1 each. Paid plans remove these limitations.

Can I use it on multiple devices?

Yes, you can activate a single license key on up to 5 devices. Please note that data is stored locally per browser, so there is no automatic sync between devices.

What happens after the Lifetime Deal sells out?

The Lifetime Deal will end, and only the monthly subscription ($29/month or $228/year) will be available.

What file formats are supported?

Currently, we support CSV and Parquet files. Support for Excel (.xlsx) and JSON is planned for future updates.

Is there a file size limit?

Each file can be up to 500MB. Performance depends on your device's available memory (RAM).

Can I share my license with my team?

No, the license is per user. However, you can use a single license on multiple devices belonging to you (e.g., your work PC and home laptop), but sharing a license key with other people is prohibited.
