Privacy Policy
Effective October 1, 2026
Blinko is a language-learning app. This policy explains what personal data Blinko collects, why, who it is shared with, and the choices and rights you have. "Blinko", "we" and "us" mean Jody Jamin, an individual developer based in the United States, who is responsible for your data (the "controller"). Contact: privacy@jodyjamin.com.
What we collect
| Data | Where it comes from |
|---|---|
| Email address and username | You, when you create an account |
| Password | You. We store only a salted hash, never the password itself. |
| Apple or Google account identifier | Apple or Google, if you sign in with them |
| Topics you request and the sets, words and sentences in your library | You, and the content we generate for you |
| Study history (answers, review schedule, streaks) | Your use of the app |
| Subscription status (plan, trial, renewal and expiry dates) | Apple. We never receive your card or payment details. |
| Your marketing email choice and when you made it | You, at signup or in Profile |
| Your agreement to our Terms, and its date | Recorded when you create an account |
| Technical logs (IP address, request times, errors) | Our servers, automatically |
Blinko has no advertising, no ad trackers and no third-party analytics, and does not track you across other companies' apps or websites. Because we don't track you, we have nothing to change in response to a browser "Do Not Track" signal, and treat every visitor as if it were on.
Why we use it
- To provide the app: your account, generating and storing your study sets, scheduling reviews, and enforcing your plan's daily limits. Legal basis: performing our contract with you.
- To keep Blinko secure: verifying your email, preventing abuse, rate limiting and investigating errors. Legal basis: our legitimate interest in a safe service.
- To send you tips, new features and offers, only if you opted in. Legal basis: your consent, which you can withdraw at any time in Profile or through the unsubscribe link in any marketing email.
- To send account emails such as verification codes and password resets. These are part of providing the service and are not marketing.
Who we share it with
We do not sell or share your personal data for advertising. We use these service providers, which process data only on our instructions:
| Provider | What they do | Data involved |
|---|---|---|
| OpenAI | Generates vocabulary and example sentences | The topics, words and language settings you request. Not your email or name. OpenAI does not use API data to train its models. |
| Render | Hosts the Blinko server (United States) | All service data in transit, and logs |
| Neon | Hosts the Blinko database (AWS, United States) | All stored account and study data |
| Delivers Blinko's emails; Google Sign-In | Your email address and message contents; your Google account identifier if you use Google Sign-In | |
| Apple | Sign in with Apple; processes subscription payments | Your Apple account identifier; purchase and subscription records |
We may also disclose data if the law requires it, or to protect the rights and safety of our users or others.
International transfers
Blinko's servers and providers are in the United States. If you use Blinko from elsewhere, including the EU, UK or Switzerland, your data is transferred to the US. Where the law requires, those transfers rely on the providers' Standard Contractual Clauses or equivalent safeguards.
How long we keep it
- Account, library, study history and subscription data: until you delete your account.
- Sign-in tokens: up to 90 days. Email verification and password reset codes: until they expire or are used.
- Records of sign-in attempts, used to block abuse: 7 days.
- Server logs: for the short periods set by our hosting provider.
When you delete your account we delete your account, library, study history and generation records, and revoke Sign in with Apple access. Apple keeps its own records of your purchases.
Your rights and choices
- Delete your account at any time in the app: You › Delete account.
- Marketing emails: turn them off in the app (You › Email me tips and offers) or use the unsubscribe link in any marketing email.
- Access, correct or export your data, or object to or restrict how we use it: email privacy@jodyjamin.com. We reply within 30 days, and may need to confirm it is your account first.
- EU, UK and Swiss residents can also complain to their local data protection authority.
- California residents have the right to know, delete and correct personal information, and to opt out of its sale or sharing. Blinko does not sell or share personal information, and we will not treat you differently for using these rights.
Children
Blinko is for people aged 13 and over. We do not knowingly collect personal data from children under 13. If you believe a child under 13 has created an account, contact us and we will delete it.
Security
Data is encrypted in transit (HTTPS). Passwords are stored as salted hashes, and access to production systems is restricted. No system is perfectly secure, but we work to protect your data and will notify you and the authorities of a breach where the law requires.
Changes to this policy
If we change this policy in a way that matters, we will update the date above and tell you in the app or by email before the change takes effect.
