Frequently asked questions

Everything you need to know before signing up.

What happens after the 14-day trial?

Once your trial ends, you'll be asked to choose a plan and enter your payment details to continue using Heatflow. If you don't subscribe, your account is paused — your data stays safe and you can reactivate at any time.

Is there a contract or minimum term?

No contract, no minimum term. Heatflow is a rolling monthly (or annual) subscription. Cancel whenever you like — right from the app or your dashboard.

How do I manage my subscription?

Solo engineers can manage their subscription from the Settings section of the app or their personal dashboard. Company owners manage all seats from the owner dashboard at app.heatflow.app.

Can I switch between Solo and Company?

Yes. If your business grows, you can upgrade to the Company plan at any time and invite your engineers in minutes. Downgrading to Solo is also available — just contact support and we'll sort it out.

What payment methods do you accept?

We accept all major credit and debit cards (Visa, Mastercard, American Express) via Stripe. All payments are processed securely. We don't store your card details.

Is my data safe if I cancel?

Your data belongs to you. If you cancel, we hold your data for 90 days so you can reactivate without losing anything. After that, you can request a full export as PDF or CSV before it's permanently deleted.

Do you offer refunds?

If you're not happy within the first 30 days of a paid subscription, contact us and we'll refund you — no questions asked. Outside of that window, refunds are assessed case by case.

Can I try it before paying?

Yes — every new account gets a full 14-day free trial with no credit card required. You get access to every feature on the Solo plan. Company plan trials are also available; contact us to set one up for your team.

How does Company plan billing work for multiple engineers?

The Company plan is priced per engineer per month. You pay for the number of active engineer seats. Adding or removing engineers adjusts your next invoice automatically — you're never charged for seats you're not using.

Do you offer discounts for larger teams?

Volume discounts are available for teams of 10 or more engineers. Get in touch via our contact page and we'll put together a quote tailored to your team size.
