Consumer Health Data Privacy Policy
Last updated: October 23, 2026
Some of what you log in Seed Oil Tracker, like the seed oil (polyunsaturated fat) you eat and how you feel, can
count as consumer health data under laws such as Washington's My Health My Data Act. This page explains exactly
what we collect, why, and how you can see it, delete it or take back your consent. It adds to our main
Privacy Policy.
1. The consumer health data we collect
- Your meal log and seed oil totals. The foods you log, their grams of polyunsaturated fat, your
daily goal, favorites and custom foods. They live on your phone. If cloud backup is on (it is on unless you
turn it off), a copy is stored on our servers under a random device ID with no name or email.
- "How I feel" check-ins (energy, skin, digestion, sleep). These stay on your phone. We never
receive them unless you join the seed oil study below.
- The seed oil study (only if you join). If you agree on the study consent screen, each day we
receive your four feel scores and that day's total grams, under a random device ID. Nothing else.
- Weekly League and camp battles (only if you join). Your average daily grams for the week and
how many days you logged, under a random device ID, so the leaderboard and the camp scores can be worked out.
- Apple Health. If you turn it on, the app writes your daily total into Apple Health on your
phone. We do not receive anything from Apple Health.
We collect this data only from you and your phone. We do not buy it, and we do not collect precise location.
2. Why we collect it
- To show your totals, streaks and stats (the app's main job).
- To restore your log if you reinstall the app or get a new phone (cloud backup).
- To run the study, the League and the camp battles, only for people who join them.
We do not use consumer health data for advertising, and we do not sell it. Ever.
3. Who we share it with
We do not share consumer health data with anyone for their own use. It is handled only by the companies that
run our service for us, under contract:
- MongoDB Atlas stores the backup, study, League and camp data.
- Render runs our servers, and Cloudflare carries traffic to them.
Our anonymous usage stats (Amplitude) never include what you eat, gram amounts or feel check-ins. Study results
we publish are only ever group totals that cannot be traced to a person.
4. Your rights and how to use them
- Delete your backup: turn off Settings > Data > cloud backup. That deletes our copy and
stops new ones.
- Leave the study or the League: leaving in the app deletes everything we stored for it.
- Anything else (confirm what we hold, get a copy, delete it, or withdraw a consent you gave):
email support@seedoiltracker.com
with the subject "Health data request". Because we never ask for your name or email, our only way to find your
data is the random ID on your phone, so the in-app switches above are the surest way; for anything else we will
work with you to find it. We answer within 45 days.
- Appeal: if we turn a request down, reply with the word "Appeal" and we will look again and
answer within 45 days. If you are still unhappy, you can contact the
Washington State Attorney General or your own state's
attorney general.
5. Changes
If we ever want to collect or share consumer health data in a new way, we will ask for your consent first and
update this page.
