Privacy Policy

This policy covers the websites and applications published by Axolve LLC, including Walking Photon and Moon Temperature.

Who we are

Axolve LLC is an Illinois limited liability company, and is the data controller for the personal data described here. You can reach us about anything in this policy at support@axolvellc.com.

What we collect

Our applications can be used without an account, and used that way they send us nothing. If you choose to sign in, we collect only what is needed to give you an account and store your work:

• Account identity. If you sign in with Google or Apple, we receive your email address and basic profile information from that provider. If you sign in with your email address, we send a one-time code to it and you enter that code — there are no passwords, so there is no password for us to store and none to reset. Either way, the email address is what identifies your account, and we send transactional email to it.
• Content you save. Simulations you choose to save are stored on our servers so you can load them again, and are private to your account unless you publish them.
• Purchases. On the web, payment is handled by Stripe, which acts as the merchant of record for the sale. On mobile, the apps are paid for once at the app store when you download them — there is no purchasing inside the apps. Either way we never see or store your card details. What we keep is a reference identifying the purchase and a record that your account is unlocked.
• Settings stored on your device. Display preferences are kept in your browser's local storage. They stay on your device and are not sent to us. This includes any location you type into Moon Temperature's “My location” view: it is used on your device to work out where the Moon sits in your sky, it is never transmitted to us, and the apps never ask your device or browser for your actual location.

Product specifics

The core of this policy is the same for every Axolve product. The differences are small and listed here.

• Walking Photon. Signed-in users can save simulations, and publish them if they choose — that is the “content you save” above. The optional music visualizer uses your microphone, with your permission; the audio is analyzed on your device in real time and is never recorded, stored, or transmitted.
• Moon Temperature. An account stores only your email address and your purchase status. The app saves no user content. You can sign in with Google, with Apple, or with a one-time code sent to your email address.

What we do not do

• We do not sell or rent personal information.
• We do not share it with third parties for advertising.
• We do not use advertising or cross-site tracking.

Service providers

We share limited data with the following providers, only as needed to run the service and each under its own privacy policy. They process data on our behalf, not for their own purposes.

• Supabase — account sign-in and the database that stores accounts and saved simulations.
• Stripe — payments for web purchases; card details are handled by Stripe and never reach us.
• Apple and Google — the app stores that sell and deliver our mobile apps, and that handle payment and refunds for them under their own terms.
• Resend — sending transactional email, such as your one-time sign-in code.
• Cloudflare — website hosting, content delivery, and DNS.
• Google and Apple — sign-in, when you choose to sign in with them.

We also use DigitalOcean for pre-release staging infrastructure.

Why we are allowed to process it

Where the law asks us to name a legal basis for processing — as the GDPR does — these are ours:

• To provide what you asked for (performance of a contract): running your account, storing and returning the work you save, sending your sign-in code, and recording that a purchase unlocked your account.
• To keep the service working and honest (legitimate interests): security, preventing abuse, and diagnosing faults. We weigh this against your interests, and it never extends to advertising or profiling.
• To meet legal obligations: keeping records of purchases for tax and accounting.
• With your consent, where a feature asks for it — for example Walking Photon's music visualizer, which does nothing until you grant microphone access, and which you can withdraw at any time in your browser or system settings.

Where your data goes

We are a United States company and our providers store data in the United States. If you are in the EEA, the UK, or Switzerland, using our services means your personal data is transferred there. For those transfers we rely on the European Commission's Standard Contractual Clauses, together with the UK Addendum where it applies; each of the providers listed above includes them in the data processing terms we are on. You can ask us for details at the address at the bottom of this page.

How we protect it

Traffic to our sites and applications is encrypted in transit, and the database holding accounts and saved work is encrypted at rest by our hosting provider. Your account tier and unlock status can only be written by our servers — never by the application running on your device, and never by you. No system is perfectly secure, and we do not claim otherwise — but we collect little enough that there is not much to lose.

Retention and deletion

We keep your account and saved content until you ask us to delete it. You can delete your account from within the app (Sign in → Delete account), or by emailing support@axolvellc.com from the address on the account. Deleting an account removes the account, the simulations saved to it, and any unlock associated with it.

Deletion takes effect immediately in our live systems. Encrypted backups are kept on a short rolling schedule and are overwritten within 30 days, after which no copy remains.

Records of a purchase are kept after deletion — by our payment processor and by us — for as long as tax, accounting and dispute-resolution law requires, which is currently seven years. These records are held under the payment processor's own privacy policy and are not linked to any remaining data once your account is gone.

Your rights

Depending on where you live — including the EU, EEA, and UK under the GDPR, and California under the CCPA/CPRA — you may have the right to access a copy of the personal data we hold about you, to correct it, to delete it, to object to or restrict certain processing, and to withdraw consent where processing relies on it. To make any of these requests, including asking for a copy of your data, email support@axolvellc.com and we will respond within the time the law allows. We will not charge you for it or treat you differently for asking. We do not sell or share your personal information, so there is no sale to opt out of.

If you are in the EEA, the UK, or Switzerland and you think we have handled your data badly, we would rather you told us first — but you have the right to complain to your national data protection authority regardless, and you do not need our permission to do it.

We do not use your data to make automated decisions that produce legal or similarly significant effects, and we do not profile you.

Children

Our applications are not directed to children under 13, and we do not knowingly collect personal information from them.

Changes

If this policy changes materially, we will update the date at the top of this page.
