What we use your email for

Short version: to let you log in, and to warn you if something happens that affects you. Nothing else.

Your email

It's your login. That's the entire reason we ask for it.
It is never sold, rented or shared with anyone. Not advertisers, not partners, not "analytics partners". There are none.
No marketing mail. No newsletters, no drip campaigns, no "we miss you" nudges.
We only ever email you about things that affect you directly — a security problem, data loss, or a change to how the app works that you'd want warned about in advance. If we can avoid emailing you, we will.

Your profile and the things you log: workouts, food, weight, habits, goals, allowances, lists.
It's stored in your account so it follows you between your phone and your computer, and kept on your device so it still works offline.
Nobody at Haruno reads your logs. There's no dashboard here showing what you ate.

Nothing, unless you opt in. The leaderboard is off until you join it, and public boards hide part of every username.
If you accept a friend, they see your weekly calories burned, active days and streaks — never your weight, your food log or your calorie deficit.
Feedback you send goes to the developer only. It isn't posted anywhere.

We count which tools get opened, once per day, so we know what's worth improving. Not what you logged in them.
The homepage totals (calories burned, goals completed) are everyone's numbers added together, with no names attached.
No ads, no trackers, no third-party analytics scripts.

You can export everything you've logged at any time from inside the app.
If you stop using Haruno, your data waits for six months in case you come back, then it's deleted.
Want it gone sooner? Send a note through Feedback in the app, or email the address below, and it's deleted — account, logs, all of it.

Haruno is a small project built by one person, still being worked on in the open. It runs on Supabase and Cloudflare, who host the database and the site.
No system is perfect. If something ever goes wrong with your data, you'll hear it from us plainly and quickly.

Questions about any of this: use the Feedback button in the app. It reaches the developer directly.
