The short version
| What | Where it goes | Who can see it |
|---|---|---|
| Numbers, dates and text you type into a tool | Stays in your browser tab | Only you |
| Files you open in a file tool (PDF, HEIC, images) | Processed in memory, never uploaded | Only you |
| Saved tool state and Pro unlock status | Your browser's localStorage | Only you |
| Advertising identifiers and cookies | Google AdSense | Google and its ad partners |
| Name, email, card and country when you buy Pro | Creem (the merchant of record) | Creem and its payment processors |
| IP address and standard request logs | Our hosting provider (Cloudflare) | Us, in aggregate, for security |
1. The tools
Every calculator, converter, planner and tracker on this site is a static web page. The arithmetic runs in JavaScript inside your browser. There is no API call carrying your inputs to a server, and no database storing them. If you close the tab, the inputs are gone unless the tool explicitly offers local saving.
File tools work the same way. When you drop a PDF or a HEIC photo into one of them, the file is read into the browser's memory and processed there. It is not transmitted anywhere. You can verify this yourself: open your browser's developer tools, switch to the Network tab, and use the tool — you will not see the file leave the page.
2. Local storage
Some tools remember what you entered so that a refresh does not wipe your work, and the Pro features remember that you unlocked them. This uses localStorage, which is stored by your browser on your own device. It is not a cookie, it is not readable by us, and it is not shared with anyone. Clearing your browser data deletes it.
3. Advertising
This site is free to use and is partly funded by advertising served by Google AdSense. Ads appear in clearly marked slots, below the tool and its result. They are never interstitials and never sit between you and your answer.
- Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites.
- Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the internet.
- You may opt out of personalised advertising by visiting Google Ads Settings, or opt out of third-party vendors' use of cookies for personalised advertising at aboutads.info.
- Google's own practices are described in the Google Privacy & Terms.
We do not control these cookies and do not receive the personal data behind them. What we see is aggregate reporting: how many impressions and clicks an ad slot received, and an estimated revenue figure.
4. Payments
Pro unlocks are sold through Creem, which acts as the merchant of record. That means Creem is the seller in the transaction: it takes the payment, issues the receipt, and handles any applicable sales tax or VAT.
We never see or store your card number. What we receive from Creem is the confirmation that a specific purchase completed, so that the unlock can be applied. Creem's handling of your data is governed by Creem's privacy policy.
5. Hosting and technical logs
The site is served by Cloudflare as a static site. Like any web host, Cloudflare processes the IP address and request headers needed to deliver a page, and keeps short-lived security logs. We use this only to keep the site available and to spot abuse — not to build profiles of individual visitors.
6. What we do not do
- We do not ask you to create an account, and there is no login.
- We do not sell, rent or trade personal data.
- We do not run third-party analytics or session-recording scripts on the tools themselves.
- We do not put email addresses collected for support into any marketing list.
7. Your rights
Depending on where you live, you may have the right to access, correct, delete, or port your personal data, to object to processing, or to withdraw consent. Because we hold almost nothing about you, most requests resolve quickly — usually by telling you we have no record.
For data held by Google as an advertising partner, use the Google Ads Settings link above. For purchase records, contact Creem. For anything else, write to [email protected] and we will respond within 30 days.
8. Children
This site is not directed at children under 13, and we do not knowingly collect personal data from them. A few tools — such as a newborn feeding log — may be used by parents to record information about a child. That information stays in the parent's browser and is never transmitted to us.
9. Changes to this policy
If the way the site handles data changes — for example if a new payment provider or ad network is added — this page will be updated and the date at the top will change. Material changes will be noted on the about page for at least 30 days.
