Sonde Data · Last updated 14 July 2026
This page is a plain-English summary of how billing works on Sonde. It forms part of our Terms of Use; if anything here conflicts with the Terms, the Terms apply.
Free — no card required. Three company lookups in total (opening a company’s page uses one and unlocks that company in full, permanently), plus one watchlist of up to 10 companies.
Pro — a monthly subscription at the price shown at checkout (currently £39 per month, including VAT). Unlimited searches, full filing parsing, complete cap tables and dilution timelines, portfolio tracking and per-company CSV export.
Pro is billed monthly in advance and renews automatically each month until you cancel. Payments are handled by Stripe on Stripe-hosted pages — we never see or store your card details. Your receipt for each payment comes by email.
We do not offer a free trial of Pro. The Free plan is how you try Sonde: it gives you 3 company lookups in full detail, at no cost and with no card. When you subscribe to Pro your card is charged immediately and access starts straight away — the 14-day full refund below is what protects you instead of a trial period.
You can cancel at any time — no notice period, no cancellation fee:
Cancellation takes effect at the end of your current billing period. You keep full Pro access until then, and no further payments are taken.
Your account moves to the Free plan — it is not deleted. Companies you have already unlocked stay viewable, watchlist entries above the Free limit are kept (though you can’t add more), and CSV files you exported while subscribed remain yours to keep for internal use, under the data-use rules in the Terms of Use.
We don’t refund the unused part of a billing period when you cancel — you keep access until the period ends instead. Beyond that:
If a renewal payment fails, Stripe retries it automatically over the following days, and you can update your card in Manage billing at any time. Your access continues during the retry period. If the payment still can’t be collected, your account moves to the Free plan.
If we change the price of Pro, we will give you at least 30 days’ notice by email or in the Service. The new price applies only from your next renewal after that notice, and you can cancel before it takes effect if you don’t want to continue.
You can close your account entirely at any time from your account settings or by contacting support@sondedata.com. If you have an active subscription, cancel it first (or ask us to). For what happens to your personal data when your account closes, see our Privacy Notice.
