Terms of Service
Last updated: 24 August 2026
These terms govern your use of the Fyrien application and the Fyrien Sync service. By creating an account or using the app, you agree to them. Fyrien is operated by Ross Wheatley as an individual sole trader ("Fyrien", "we", "us").
The service
Fyrien is a local-first application for organising notes, tasks, projects and related content as files on your own device. Fyrien Sync is an optional paid service that stores an encrypted copy of your vault so it can be synchronised between your devices, and delivers optional reminders.
Fyrien is under active development. Features may change, and some are offered on an early-access basis where behaviour may be incomplete or subject to revision.
Your account
You are responsible for keeping your account credentials, your sync passphrase and your recovery key secure, and for activity that takes place under your account. You must provide accurate registration information and be old enough to form a binding contract where you live. Notify us promptly at [email protected] if you believe your account has been compromised.
Encryption, and what it means for recovery
Sync encrypts your content on your device before uploading it. We do not hold your sync passphrase, your recovery key, or any key derived from them. If you lose all of them, your synced content cannot be decrypted by us or by anyone else, and it cannot be recovered. This is a consequence of the design, not a support limitation, and you accept this risk by using Sync. Keep your own backups of anything you cannot afford to lose — your vault files on your own device are ordinary files and can be copied at any time.
Your content
Your content remains yours. You grant us only the limited permission needed to store, transmit and synchronise the encrypted copy of it at your direction, in order to operate the service. We claim no ownership of it, and we do not use it to develop or train models. We cannot read it.
Subscriptions and payment
Paid plans are billed in advance on a recurring basis through our payment processor until cancelled. You may cancel at any time; your subscription then continues until the end of the paid period and is not renewed. Unless required by law, fees already paid are non-refundable. We will give reasonable advance notice of any price change, which will take effect at your next renewal.
If a subscription lapses, syncing stops. Your data on your own devices is unaffected and remains fully usable — the app does not stop working locally.
Acceptable use
You agree not to:
- use the service to store or distribute unlawful material;
- attempt to gain unauthorised access to the service, other users' data, or the systems that run it;
- interfere with or place an unreasonable load on the service, including by circumventing usage limits;
- resell or redistribute the service without our written agreement.
Third-party services
If you connect a third-party service such as Google Calendar, your use of that service is governed by that provider's own terms, and we are not responsible for it. You can disconnect it at any time. What we do with data from those services is described in our Privacy Policy.
Availability
We aim to keep Sync available and reliable, but we do not guarantee uninterrupted service. Maintenance, outages of upstream providers, and faults can interrupt it. Because Fyrien is local-first, an interruption to Sync does not prevent you from using your vault on your device.
Disclaimers
Except where the law says otherwise, the service is provided "as is" and "as available", without warranties of any kind, whether express or implied, including fitness for a particular purpose and non-infringement. Some jurisdictions do not allow the exclusion of certain warranties, and nothing here limits rights you have under consumer law that cannot be excluded.
Limitation of liability
To the extent permitted by law, we are not liable for indirect, incidental, special or consequential loss, or for loss of data, profits or goodwill. Our total liability arising out of or relating to the service is limited to the amount you paid us in the twelve months before the event giving rise to the claim. Nothing in these terms excludes liability that cannot lawfully be excluded.
Suspension and termination
You may stop using the service and delete your account at any time. We may suspend or terminate an account that breaches these terms, or where required by law, and will give notice where it is reasonable to do so. On termination, encrypted vault data held on our servers is deleted; your local files are unaffected.
Changes to these terms
We may update these terms. For material changes we will give notice to account holders by email or in the app before they take effect. Continuing to use the service after that point means you accept the updated terms.
Governing law
These terms are governed by the laws of New South Wales, Australia. You and we submit to the non-exclusive jurisdiction of the courts of New South Wales and the courts entitled to hear appeals from them. This does not affect any mandatory rights you have under the law of your own country of residence, and nothing in these terms excludes, restricts or modifies any guarantee, right or remedy you have under the Australian Consumer Law that cannot lawfully be excluded.
