Solaris — Terms of Service

Effective date: 2026-10-05 Version: 1.4

These Terms govern the Solaris account, the sync service, the licence service and the website at https://northlanestudio.dev (together, the "Service"), all operated by Northlane Studio ("Northlane Studio", "we", "us").

The Software you install on your computer is covered by a separate document, the End User License Agreement. You can use Solaris without ever creating an account; these Terms only start to matter when you do.

By creating an account or using the Service you accept these Terms.

1. Who can use the Service

You must be at least 16 years old, or the age of digital consent where you live, whichever is higher. If you are using the Service on behalf of a company, you confirm you can bind that company.

2. Your account

• Give us a real email address you control. It is how we identify you, how we deliver your licence and how we reach you if something goes wrong.
• Your account is a Northlane Studio account: the same email and password sign you in to every Northlane Studio app. There is no sign-in through other services.
• You are responsible for your password and for everything done through your account. Use a password you do not use anywhere else, and we recommend turning on two-step verification. If you turn it on, keep your recovery codes somewhere safe: without your phone and without those codes, we may need to verify your identity before we can switch it off for you.
• Tell us immediately at [email protected] if you think somebody else got in.
• One account is for one person. Do not share it.

We may keep an account signed in on several devices, and we may sign devices out — for example, when you change your password.

3. What the Service does

Solaris Sync is a personal locker, not a library and not a service to the public. Rules that follow from that, and that you accept by using it:

1. Upload only files you are entitled to store. Music you bought, ripped from your own media, recorded, or are otherwise licensed to keep. Do not upload anything you do not have the right to.
2. It is private by design. Files are stored per account. There is no sharing, no public link and no way for another user to reach your files — and you may not try to make them reachable.
3. We do not inspect what you store, but if a rights holder sends us a valid notice under our copyright policy, we will act on it, which may mean removing files or suspending the account.
4. Solaris Sync needs an active subscription — the Solaris Sync subscription. While it is active you can upload and download; there is no quota you are meant to reach, only a high cap so one account cannot fill the server. If the plan ends, your files are not deleted — you can still download them — but new uploads stop until you resubscribe. We give you at least 30 days' notice before removing anything for a storage or plan reason.
5. Keep your own copies. The locker is a convenience, not a backup service: see clause 10.

The data part of sync stores only text — titles, artists, paths, ratings, play counts, settings.

3b. Music from SoundCloud

Solaris can search and play music from SoundCloud through SoundCloud's official API. That music belongs to its creators and is provided by SoundCloud under SoundCloud's own terms; Solaris shows who made each track and links back to it on SoundCloud.

• Solaris and Northlane Studio are not affiliated with, sponsored by or endorsed by SoundCloud. "SoundCloud" is a trademark of its owner.
• SoundCloud decides what can be played. Tracks can be blocked in your country, limited to a 30-second preview, or removed at any time, and SoundCloud limits how much the whole app can play per day. When that limit is reached, SoundCloud music may stop loading for a while; your own files keep working.
• You may not use Solaris to download, record, redistribute or otherwise copy SoundCloud music, or to get around SoundCloud's limits.

4. Paying for Pro

Solaris Pro is a one-time payment (MXN 399 / USD 19.99): a lifetime licence with no subscription. Solaris Sync is not part of Pro; it is an optional monthly subscription (section 4b).

• Payment is processed by Stripe. We are the seller — Northlane Studio, not Stripe — and we are responsible for your invoice and for any tax we must charge. Stripe only handles the card transaction; we never see or store your card number.
• Prices are shown in MXN (Mexico) / USD and include any tax we are required to charge. Nothing is added at checkout. Your bank's own currency-conversion or foreign-transaction fee, if any, is between you and your bank.
• Solaris Sync renews automatically until you cancel. Cancel any time from your account: cancelling stops the next charge, and what you paid for stays active until the end of that period.
• The lifetime licence is delivered to your account and by email. Keep it: it is what proves you bought Pro, and it works offline.
• Refunds are governed by the Refund Policy.
• If a payment is reversed or charged back, we may deactivate the licence or subscription it paid for.

4b. Solaris Sync on its own

• Solaris Sync is a subscription of MXN 49 / USD 2.99 a month, with or without Pro, charged through Stripe, that renews automatically until you cancel.
• Cancel any time. Cancelling stops the next charge; Sync stays active until the end of the period you already paid for, and then uploads stop.
• Your files are never deleted for non-payment. After the subscription ends you can still sign in and download everything in your locker; you just cannot upload anything new until you resubscribe.
• A period you have started is not refunded just because you cancelled part way through it, except where the law where you live requires it.

5. Rules of use

Do not:

1. break into, probe, or overload the Service, or try to read other people's data;
2. use the Service to store or distribute anything illegal;
3. resell, redistribute or automate access to the Service without our written permission;
4. use the licence service to make, share or use licence keys you did not buy;
5. impersonate anybody, or lie about who you are.

If you break these rules we may suspend or close your account. Where it is reasonable to do so, we will tell you why first.

6. Availability

We will try to keep the Service up, but we do not promise any level of availability. It can go down for maintenance, for a provider's outage, or permanently.

Solaris keeps working without the Service. The player, the library, the local files and an already-activated Pro licence all work offline. If the Service disappears, you lose sync and account management, not your music player and not the Pro features you paid for — that is a deliberate design decision and it is part of this contract.

If we ever shut the Service down for good, we will give at least 90 days' notice by email to the address on your account, and during that period you will be able to export your synced data.

7. Your content

Whatever you sync stays yours. You give us only the narrow permission we need to run the Service: to store your data, copy it between your devices, and back it up. We do not sell it, we do not mine it, and we do not use it to train anything. Details in the Privacy Policy.

You are responsible for having the right to whatever you put in. If a rights holder tells us something in your account infringes their rights, we follow COPYRIGHT.md.

8. Our content

The Solaris name, the Solaris and Northlane Studio logos, the website and the Software are ours. These Terms give you no right to use our trade marks, except to refer to the product truthfully.

9. Closing your account

You can close your account at any time from the app or by writing to [email protected]. When you do:

• your synced data and every audio file you stored are deleted within 30 days (backups can hold them for up to 30 more);
• a lifetime Pro licence stays valid — it is a licence to the Software, and it keeps working offline; a Pro subscription (and the Solaris Sync it includes) ends when the account is closed;
• we keep the minimum record of the purchase that tax and accounting law requires us to keep.

We can close or suspend your account if you break these Terms, if we are required to by law, or if the Service shuts down under clause 6.

10. No warranty, and limits on liability

The Service is provided "as is" and "as available", without warranty of any kind, to the maximum extent the law allows.

To the maximum extent the law allows, our total liability arising out of the Service is capped at the greater of MXN 1,590 or the amount you paid us in the 12 months before the claim, and we are not liable for indirect or consequential loss, lost profits or lost data.

Nothing here removes rights you have as a consumer under the mandatory law of the country you live in.

11. Changes to these Terms

We may change these Terms. If a change materially reduces your rights we will tell you by email or in the app at least 30 days before it takes effect, and if you do not accept it you may close your account and, where the law requires, get a proportional refund. Every version is dated and kept at https://northlanestudio.dev/legal.

12. Law and disputes

These Terms are governed by the laws of the United Mexican States, and the courts of Mexico City, Mexico have jurisdiction — except that a consumer keeps the mandatory protection and the local courts of the country they live in.

Before going to court, please write to [email protected]. Most things are a misunderstanding and get solved in one email.
