Privacy Policy
Kizy — AI Accountability Coach
Last updated: July 7, 2026
Kizy ("we", "us") is operated by Arslan Assankulov, an individual developer based in Kazakhstan. This policy explains what data Kizy collects, why, where it goes, and how you can delete it.
What we collect
We collect only what the product needs to function:
- Email address — used to sign you in via magic link. We have no passwords.
- Display name — the name you provide at onboarding, so Kizy can address you.
- Your goal — the goal title, why it matters to you, and its target date.
- Chat messages — everything you and Kizy say to each other.
- Check-in and commitment history — records of your daily check-ins, commitments, and streaks, derived from your conversations.
- Push notification token — a device token issued by Apple so we can send you your daily check-in.
- Timezone and preferred check-in time — so your check-in arrives when you chose.
We do not collect: location, contacts, photos, browsing history, advertising identifiers, or anything from other apps. Kizy contains no ads and no third-party analytics or tracking SDKs.
How your data is used
- To deliver the core product: proactive daily check-ins that reference your specific goal and history.
- To generate Kizy's responses. Your messages and goal context are sent to OpenAI (our AI provider) to classify and generate replies. Per OpenAI's API data usage policies, API data is not used to train their models.
- To retrieve relevant history: your messages are converted into embeddings (numerical representations) so Kizy can recall relevant past conversations when responding.
- To schedule and send your daily push notification via Apple Push Notification service.
- To send you sign-in (magic link) emails via Resend, our email delivery provider.
We do not sell your data. We do not share it with anyone except the service providers listed below, and only to the extent required to run the product.
Where your data lives
Your data is stored in a Supabase (Postgres) database hosted in the European Union (eu-central-1, Frankfurt). Access is restricted at the database level so that each user can only access their own data.
Service providers
| Provider | Purpose | What they process |
|---|---|---|
| Supabase | Database, authentication | All data listed above |
| OpenAI | AI classification and response generation | Your messages and goal context |
| Apple (APNs) | Push notification delivery | Push token, notification content |
| Resend | Sign-in email delivery | Your email address |
| Railway | Server hosting | Data in transit through our servers |
Payments
Subscriptions are billed entirely through Apple's App Store. We never see or store your payment details — Apple handles all of it under Apple's own privacy policy.
Data retention and deletion
Your data is retained while your account exists. You can delete your account at any time inside the app: ⋯ menu → Delete Account → confirm. Deletion is immediate and permanent: your account and all associated data (profile, goal, messages, check-ins, commitments) are erased from our database. There is no soft-delete or grace period.
You can also email us at support@kizy.app from your registered address and we will delete your account for you.
Your rights
Depending on where you live (including under the EU GDPR), you may have rights to access, correct, export, or erase your personal data, and to object to or restrict certain processing. The deletion right is built into the app as described above. For anything else, email support@kizy.app and we will respond within a reasonable time, and in any case within the period required by applicable law.
Children
Kizy is not directed at children and is intended for users aged 13 and over. We do not knowingly collect data from children. If you believe a child has created an account, contact us and we will delete it.
Changes
If we materially change this policy, we will update this page and the date above. Continued use of Kizy after changes means you accept the updated policy.
