Privacy Policy
Last updated 2026-10-01
In plain English
- We keep your email, your licence key, the data you put in, and how you use the product.
- We never sell your data. We do not use it to train AI.
- Stripe takes your payment. We never see your card number.
- A few companies handle data for us so the product works: Stripe, Supabase, Resend, Anthropic, PostHog, Meta, Sentry, Railway, Cloudflare.
- Our home page may show ads from Google. The app itself has no ads, and your plan is never shared with ad companies.
- We ask before we use cookies to measure our ads. If you say no, they never load.
- Your data is stored in the United States.
- You can download your data or delete your account from inside the product.
This summary is here to make the page easier to read. It is not the full text. If the two ever seem to differ, the full text below is what counts.
What we collect
- Your account. Email address and licence key.
- What you put in. The data you enter or import, which is yours and which we process only to run the product for you.
- How the product is used. Pages opened, features used, errors hit — so we can fix what breaks and improve what does not.
What we do not do
- We do not sell your data.
- We do not use your content to train anyone's models.
- We do not see your card number. Stripe handles payment.

Ads on our home page
Our home page may show ads from other companies. The ads come from Google AdSense. Each ad is marked "Advertisement".
Google and its partners may use cookies to show you ads. The ads can be based on your past visits to our site or to other sites. You can read how Google uses information from sites that use its services. You can turn off ads based on your visits in Google's Ads Settings, or turn off many ad companies at once at aboutads.info.
The planner app itself shows no ads. The numbers and plans you put in the app are never shared with any ad company.
Cookies and ad measurement
We ask before we use any cookie the site does not need to work. You see the choice at the bottom of the page the first time you visit. If you say no, none of the tools below load, and the app works the same.
If you say yes, we load the Meta (Facebook and Instagram) pixel. It tells us which of our ads brought you here, and whether you opened the free demo, started a trial or paid. We may also load Google Analytics, TikTok, LinkedIn and PostHog, to count visits the same way.
When you pay, and only if you said yes, we also send Meta a scrambled copy of your email (a one-way "hash") and the amount, so it can match the payment to an ad. We never send the numbers in your plan.
You can change your mind at any time. Use the "Cookie choices" link at the bottom of our home page.
Where it is stored, and for how long
Data is stored in the United States. When you delete your account, we keep it for no time in the live database: it is erased when you delete it. Copies can remain in our database backups until those backups expire.
Your rights
You can export everything the product holds about you, and you can delete your account, from inside the product — not by emailing us and waiting. If you are in a jurisdiction with statutory data rights (the UK, the EU, California and others), those rights apply to you and these controls are how you exercise them.
Security
What we actually do is on the security page, stated plainly enough that you can check it.
Changes
Material changes are announced by email before they take effect.
