[REVIEW] still need confirmation
before launch. Questions? support@learngravity.com.
1. Who we are
Gravity is a language-learning app and accompanying website operated by Heimdall Space, a company registered in Canada. In this policy, "Gravity" refers to the product; "Heimdall Space", "we", "us" and "our" refer to the operating company. This policy explains what information we collect when you visit our website or use the Gravity mobile app, why we collect it, and what choices you have.
2. What we collect
We try to collect as little as possible. Specifically:
- Visiting the website. Anonymous usage analytics — pages viewed, time on page, referring site or ad, UTM parameters, country (derived from IP), browser type, device type, and screen size. We do not collect your name, email, or any identifier you don't deliberately provide.
- Using the mobile app. If you create an account, the email and password you provide. Anonymous usage events (which features you use, study session length) and error/crash diagnostics. Content you capture in the app (photos, audio, notes) is stored to provide your learning experience.
- Contacting us. Your email address and the contents of your message.
3. Why we collect it
To run the service, improve it, and understand how people find us. Specifically:
- Performance & debugging — fixing crashes, improving slow pages.
- Product analytics — understanding which features help people learn.
- Marketing attribution — knowing which posts, ads, or referrals send curious people to us, so we can do more of what works.
- Account management — only if you create an account in the app.
For visitors in the EEA, UK, Switzerland, or other jurisdictions requiring it, we rely on your consent for analytics cookies (collected via our consent banner). For visitors elsewhere, we rely on legitimate interest to understand site performance and traffic sources, and you can opt out at any time.
4. Third-party services we use
We use a small number of trusted providers to operate Gravity:
- PostHog — product analytics. Hosted in the United States. PostHog privacy policy.
- Loops — handles our waitlist email list and sends launch announcements. Stores only your email address. Loops privacy policy.
- Cloudflare Pages — serves this website from a global CDN.
- Apple App Store and Google Play — distribute the Gravity mobile app and provide store-level analytics independent of us.
- [REVIEW: any future tools — Sentry for errors, payment processor, etc.]
These providers act as data processors on our behalf and are bound by data-processing agreements.
5. How long we keep your data
- Anonymous website analytics: up to 12 months in PostHog.
- Account information (mobile app): retained while your account is active. Deleted or anonymized within 30 days of account deletion.
- User-generated content (captures, notes): retained while your account is active.
- Support emails: up to 24 months after the last reply, for reference.
6. Cookies and local storage
Our website uses a small number of cookies and localStorage entries:
gravity.theme— remembers your light/dark mode preference (strictly necessary).gravity.consent.v1— remembers your tracking preference (strictly necessary).__ph_opt_in_out_*and related PostHog cookies — only set after you accept analytics. Used to recognize returning visitors anonymously.
You can change your choice at any time using the Privacy preferences link in the footer or here.
7. Your rights
Depending on where you live, you have rights regarding your personal data. Residents of the EEA, UK, Switzerland, Canada, and California (and similar jurisdictions) may request to:
- Access the personal data we hold about you.
- Correct inaccurate data.
- Delete your data ("right to erasure").
- Restrict or object to certain processing.
- Receive your data in a portable format.
- Withdraw consent for analytics at any time.
- Lodge a complaint with your local data protection authority.
To exercise any of these rights, email support@learngravity.com. We respond within 30 days.
8. International data transfers
Some of our service providers (notably PostHog) are based in the United States. When data from EEA/UK/Swiss visitors is transferred to the US, we rely on appropriate safeguards under GDPR, including the EU–US Data Privacy Framework and/or Standard Contractual Clauses, as applicable to each provider.
9. Children
Gravity is intended for users 13 and older. We do not knowingly collect personal information from children under 13. In jurisdictions where the minimum age for digital consent is higher (16 in parts of the EU), the higher age applies. If you believe a child has provided us with personal information without parental consent, please contact support@learngravity.com and we will delete it.
10. Security
We use industry-standard technical and organizational measures — encryption in transit (HTTPS), access controls on production data, and vendor due diligence — to protect your information. No system is perfectly secure; we will notify affected users if a breach materially affects their data, as required by law.
11. Changes to this policy
We may update this policy as Gravity grows. When we make material changes, we'll update the "Last updated" date at the top and, for significant changes, notify users by email or an in-app/website notice. Continued use of Gravity after changes take effect means you accept the updated policy.
