Privacy policy
Last updated: [date you publish]
The short version
- We collect only what Solvy needs to work: the problems you solve, your settings, and an account ID.
- No adverts. We never sell your data or use it to track you across other apps or websites.
- When Solvy explains a problem, the problem’s text is sent to our AI provider, DeepSeek, which processes it in China. We never send your name, email or account ID with it.
- You can delete your account and everything in it at any time: Settings → Delete account.
Who we are
Solvy is made by ORBIXYLABS LTD, a company registered in England and Wales (company number 17177342), whose registered office is Office 1160, 60 Tottenham Court Road, London, W1T 2EW (“we”, “us”). We are the controller of your personal data under the UK GDPR and the Data Protection Act 2018. ICO registration number: [number].
Questions about privacy: support@orbixylabs.com.
What we collect
| Information | What it is | Why |
|---|---|---|
| Account ID | A random identifier created when you first open Solvy, even if you don’t sign in. | To keep your history and settings together and apply the daily free limit. |
| Sign-in details | If you sign in: your email address, and your name if Apple or Google share it. With Sign in with Apple you can hide your real email. | So you can use Solvy on more than one device and keep your history. |
| Problems and solutions | What you type, ask or calculate, and the answers and steps Solvy gives. Whether you saved a problem. | To solve and explain problems and show your History. |
| Photos of problems | When scanning is available: the photo you take of a problem. | To read the problem from the photo. |
| Settings and time zone | For example angle unit and decimal places, and your phone’s time zone (not your location). | To remember your preferences and reset free solves at your midnight. |
| Usage and subscription | How many solves you’ve used today, and whether you have Solvy Pro. | To apply the free limit and give Pro users unlimited solves. |
| Reports and feedback | Anything you send with “Report this problem” or “Send feedback”, and your app version. | To fix mistakes and improve Solvy. |
| Support emails | Your email address and message if you contact us. | To reply to you. |
| Technical data | Device model, operating system, app version, crash reports, and IP address in server logs. | To keep Solvy secure and working, and fix crashes. |
We don’t collect your precise location, contacts, photos you haven’t chosen to scan, or advertising identifiers. Please don’t type personal details (such as names or addresses) into problems.
How we use it, and our legal basis
- To provide Solvy (solving problems, History, settings, free limit, subscriptions): necessary to perform our agreement with you.
- To keep Solvy secure, fix bugs and improve answers, including reviewing reports and crash data: our legitimate interest in running a reliable, safe service.
- To reply to you when you contact us: our legitimate interest in providing support.
- To meet legal obligations, such as tax records for purchases.
We don’t use your data for advertising, sell it, or build marketing profiles. We don’t make decisions about you based solely on automated processing that have legal or similarly significant effects.
Who we share it with
We use trusted service providers who process data only on our instructions:
| Provider | What for | What they receive |
|---|---|---|
| Supabase | Accounts, database and file storage | Everything listed above. Hosted in the European Union (Frankfurt, Germany). |
| Railway | Runs our maths engine | The text of the problem only, with no account details. |
| DeepSeek | AI that explains steps and reads word problems | The text of the problem and its checked answer only, with no name, email or account ID. Processed in China. |
| Google Firebase (Crashlytics) | Crash reports | Technical data about crashes. |
| Mathpix | Reading problems from photos (when scanning is available) | The photo of the problem. |
| Apple, Google and RevenueCat | Sign-in and Solvy Pro subscriptions (when available) | What’s needed to sign you in and manage your subscription. We never see your payment card details. |
We may also share information if the law requires it, or to protect the safety of our users.
International transfers
Some providers process data outside the UK, including in the United States and, for DeepSeek, in China. Where this happens we use safeguards recognised under UK data protection law, such as the International Data Transfer Agreement. [Confirm the safeguard in place for each provider.] To reduce the risk, we only send the text of the problem to DeepSeek, never information that identifies you.
Children and young people
Solvy is for people aged 13 and over. [Confirm your minimum age.] Because many of our users are students under 18, we follow the ICO’s Age Appropriate Design Code: privacy-protective settings by default, no adverts, no profiling for marketing, no location tracking, and only the data needed to provide the service. If you believe a child under 13 is using Solvy, please contact us and we’ll delete their data.
How long we keep it
| Information | How long |
|---|---|
| Account, History, settings | Until you delete them or your account. Accounts not used for 12 months are deleted. |
| Items you delete, or “Clear” from History | Removed straight away from our live systems; backups expire within 1 month. |
| Reports and feedback | Up to 1 month after we’ve dealt with them, or until your account is deleted. |
| Server logs and crash reports | Up to 1 month. |
| Purchase records | As long as tax law requires (usually 6 years). |
Your rights
You can ask to access, correct, delete or receive a copy of your data, or object to or restrict how we use it. The quickest way to delete everything is Settings → Delete account in the app. For anything else, email support@orbixylabs.com; we’ll reply within one month. If you haven’t signed in, tell us that in your email and we’ll help you find your data.
If you’re unhappy with how we’ve handled your data, you can complain to the Information Commissioner’s Office at ico.org.uk or on 0303 123 1113. We’d appreciate the chance to help first.
Security
Data is encrypted in transit, access to your records is restricted to your own account by database security rules, and our secret keys never ship in the app. No system is perfectly secure, but we work to protect your information and will tell you and the ICO if a breach affects you where the law requires.
Changes to this policy
If we make important changes, we’ll tell you in the app before they take effect. The date at the top shows when this policy last changed.
