Privacy Policy
Effective 29 July 2026
1. What this site collects directly
Nothing. There is no sign-up, no login, no comments and no contact form. There is nowhere to enter a name, an address or any other personal detail, so no personal data is stored.
Numbers you type into the calculators and simulators are computed entirely in your browser and are never sent to a server.
2. Third-party services
Although this site collects nothing itself, the services below are embedded as scripts and process visit data under their own policies.
| Service | Purpose | Status |
|---|---|---|
| Google AdSense | Advertising on English pages | Not in use |
| Kakao AdFit | Advertising on Korean pages | Active |
| Coupang Partners | Affiliate banner on Korean pages | Active |
| Cloudflare | Hosting and security. Access logs including IP addresses | Active |
This site does not use visitor analytics such as Google Analytics. If that changes, this page will be updated first.
3. Cookies
Advertising services use cookies. Specifically:
- Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites.
- Google's use of advertising cookies enables it and its partners to serve ads based on visits to this and other sites on the Internet.
- Kakao AdFit may likewise collect behavioural data for personalised advertising, and Coupang Partners uses cookies to attribute referrals and purchases.
How to opt out
- Disable personalised Google advertising at Google Ads Settings.
- Opt out of third-party vendors generally at aboutads.info or the NAI opt-out .
- You may also block cookies in your browser. The guides and calculators on this site work normally either way.
4. Affiliate disclosure
As a Coupang Partners affiliate, this site earns a commission from qualifying purchases. The same disclosure is shown next to the banner itself.
5. Retention
Because no personal data is stored, there is no retention period or deletion process on this side. Data collected by third parties is retained under their own policies.
6. Your rights
There is no personal data held here to access, correct or delete. For data collected by advertising vendors, use the opt-out links in section 3 or contact those vendors directly.
