What we collect
If you sign up for emails
- Your email address.
- The calculator result shown when you signed up (salary entered, estimated limit), if you used the calculator form.
- How you found the site: campaign tags in the link you followed, the website that referred you, the first page you visited, and which form you used.
- A friend’s referral code, if you arrived through one.
- Your country, as reported by our hosting provider at signup, and the dates you signed up, confirmed and unsubscribed.
We do not store your IP address with your signup.
If you click a link to a donation portal
We record which portal, the page the link was on, how you found the site, your country and the time. This record is not linked to your email address.
In your browser
The site stores a few items in your browser’s local storage: how you first arrived, a friend’s referral code, your own referral code after you confirm, and, if you use the donation tracker, the donations you enter. They stay on your device, except that the first two are sent to us when you sign up or click a portal link. Clearing your browser’s site data removes them. We do not use advertising cookies.
Why we collect it
- To send the emails you asked for: a confirmation, the checklist, deadline reminders, and referral rewards.
- To keep a record that you opted in, as Japanese law on commercial email requires.
- To credit referrals and to understand which channels and pages bring readers.
We do not sell your data and do not share your email address with donation portals or advertisers.
Who processes it
- Cloudflare hosts the site and the database, and provides the bot check on signup forms (Turnstile).
- Resend delivers our emails.
These providers may process data outside Japan.
Links to other sites
Donation portals and affiliate networks set their own cookies when you follow a link to them and handle your data under their own policies. See the affiliate disclosure.
Your choices
- Unsubscribe: every email has a one-click unsubscribe link. We keep your address marked as unsubscribed so that we do not email you again.
- Access, correction or deletion: write to hello@gradflowlab.com from the address concerned and we will act on it within 30 days.
Changes
If this policy changes in a way that affects subscribers, we will say so in the next email we send.
