Transparent, pay-as-you-go pricing

The Light Data uses credits instead of subscriptions: top up what you need and pay only when a task succeeds. Many tools are free, no top-up needed.

How do credits work?

Prices are always up to date

Every price on this page is read straight from the billing system, so it always matches the credits actually charged in the app.

Pricing and payment questions

Are failed submissions charged?

No. Credits are charged only for responses Google Forms records successfully. Credits held for failed or unsent submissions return to your balance when the job ends.

What if I stop a job halfway?

You can stop at any time. Only submissions sent successfully before you stopped are charged; the credits held for the rest are returned.

How soon do topped-up credits arrive?

If you transfer the exact amount with the exact transfer description (the order code) shown on the Wallet page, credits are usually added automatically within a few minutes. If it takes too long, message support with a screenshot of the transaction.

Which tools are free?

Drawing models and reading result tables, building questionnaires with AI, reading Google Forms, previewing responses, downloading the Excel template and reviewing the suggested codebook cost no credits.

Can I get a refund for credits I topped up?

See the Payment & refund policy for details. If you transferred money but didn’t receive your credits, we’ll help sort it out.
