Privacy Policy
Last updated: October 11, 2026
Streakful (the website and the iOS app) is operated by Mikel White ("we"). This policy explains what we collect, why, who it's shared with, and how to delete it.
What we collect
- Your account: your email address, your password, and the leaderboard name you choose, if any. We store the password only as a salted hash, never the password itself. We also record whether you've verified your email.
- What you do in Streakful: the habits you create (name and emoji), the days you check them off, Streak Insurance you use, and your Brain Training scores with the day you played.
- A few moments in the app: when you reach a free plan's limit, start a purchase, or a plan switches on. We record these on our own server, linked to your account, only to see whether our free plans and prices work.
- Your timezone (for example "America/New_York"), sent by your browser or the app, so your day, streaks and daily free plays roll over at your midnight.
- Purchases: on the website, payments are handled by Stripe. We never see or store your card number; we keep Stripe's customer and subscription IDs and your subscription's status. In the iOS app, purchases go through Apple; we keep the transaction ID and status Apple sends us to confirm your subscription, and attach a random identifier to your purchases so Apple's renewal and refund notices reach the right account.
- Cookies and local storage: a session cookie that keeps you logged in, and a cookie with your timezone. The website also remembers your sound on/off choice in your browser's local storage, which never leaves your device.
We don't use advertising, tracking or third-party analytics tools, and we don't sell your data.
How we use it
Only to run Streakful: to keep you logged in, track your habits and streaks, compute scores and leaderboards, give you the plan you paid for, and send account emails (email verification and password reset) and, only if you turn them on, daily reminders: an email, or a notification your iPhone schedules itself.
Who can see it
- Other Streakful users see the Brain Training leaderboards, which show your leaderboard name — one you choose, or an automatic one like "Player 3F9A" — next to your best score for each game. Your email address is never shown.
- Service providers who process data on our behalf: Stripe (website payments), Apple (App Store purchases), our email delivery provider (account and reminder emails), and our hosting provider.
- Authorities, if the law requires it.
Keeping and deleting your data
We keep your data while your account exists. You can delete your account at any time: in the iOS app under Account → Delete Account, or on the website from your Account page. Deleting your account immediately and permanently removes your account, habits, check-ins, scores and subscription records from our database, and removes you from the leaderboards. Any subscription you bought on the website is cancelled at the same time.
A subscription bought through the App Store isn't stopped by deleting your account; cancel it in your iPhone's Settings. Stripe and Apple keep their own records of payments under their own privacy policies.
Security
Passwords are stored only as salted hashes, and data is sent over encrypted (HTTPS) connections.
Children
Streakful isn't directed at children under 13, and we don't knowingly collect their information. If you believe a child has created an account, contact us and we'll delete it.
Your choices and rights
You can see and change your habits in the app, and delete your account and all its data yourself as described above. For anything else — including a copy of your data — contact us at mikelwhite124@gmail.com.
Changes
If we change this policy, we'll update the date at the top of this page.
