Terms of Service

Last updated: 5 May 2026 · Version 2.0

Plain-English summary: StellarGauge is a BLE-based smart-monitoring service operated by Perlicom Systems Ltd, an Irish company. By creating an account or using the app you agree to these terms. The Service is sold as-is for informational monitoring; readings can drift, and you must always verify physical levels before relying on a reading for safety, ordering or billing.

1. Who we are

The Service is provided by:

Company: Perlicom Systems Ltd (T/A StellarGauge)
Registered address: Dalgin, Milltown, Tuam, Co. Galway, Ireland
Support / legal contact: support@stellargauge.com

2. The Service

StellarGauge provides:

A mobile application for Android (and, in future, iOS) that pairs with StellarGauge BLE devices over Bluetooth Low Energy.
A web dashboard for reviewing devices, history and alerts.
Cloud storage of readings, alert configuration, history and account preferences.
Optional Premium features (multi-device support, extended history, alerts, export, analytics) under an active subscription.

Hardware (oil tank monitors, future temperature controllers and security cameras) is sold separately under its own warranty terms shipped with the device.

3. Eligibility & account

You must be at least 16 years old, or the digital-services consent age in your country, whichever is higher.
You sign in with a valid Google account. You are responsible for safeguarding access to that account.
You must provide accurate information and keep your contact email current — we use it for security alerts, billing and service notices.
One human person per account. You may not share credentials.

4. Subscription & billing

4.1 Free tier

The free tier supports one device, no history beyond the most recent reading, and no premium alerts/export/analytics. We may adjust free-tier limits with reasonable notice.

4.2 Premium

Price: €3.49/month (or current published price on stellargauge.com), billed via Revolut Merchant.
Includes: up to 10 devices, 365-day history, smart alerts, CSV export, analytics dashboards, priority support.
Renewal: auto-renews monthly until cancelled. You can cancel from the app's Billing screen at any time; cancellation takes effect at the end of the current billing period.
Refunds: we offer a 14-day cooling-off period for first-time subscribers in line with EU consumer law. After that, payments are non-refundable except where required by law.
Failed payments: we'll retry within 7 days; after which Premium features lock back to free-tier limits until a successful charge clears.

5. Accuracy & safety disclaimer

StellarGauge is an informational tool. Tank-level, temperature, signal and battery readings can drift due to sensor calibration, low battery, BLE interference, firmware issues, network outages or wireless reflections. Always verify the physical state of a tank, system or property before placing an order, scheduling a refill, or making a safety decision. You agree not to use StellarGauge as the sole basis for any safety-critical action.

6. Acceptable use

You will not:

Reverse-engineer, decompile or attempt to extract source code or BLE protocol secrets.
Probe, scan, scrape or load-test our infrastructure.
Use the Service to harass, threaten or impersonate any person or entity.
Upload data containing personal information about third parties without their consent.
Resell, sublicense or operate the Service on behalf of a third party without a written commercial agreement with us.

7. Intellectual property

The Service, the StellarGauge name and logo, all firmware, source code, designs and documentation are owned by Perlicom Systems Ltd. You receive a personal, non-transferable, revocable licence to use the Service while these Terms are in effect. All readings and notes you create are yours; you grant us a limited licence to host them so we can run the Service for you.

8. Service availability & changes

We aim for high uptime but the Service is provided "as available" — Bluetooth, mobile networks, your phone's OS scheduler, and our cloud upstreams can all fail in ways we cannot prevent. Scheduled maintenance is announced in-app where possible. We may add, change or remove features at any time; we will not remove a feature you actively paid for in the current billing period without offering a pro-rata refund.

9. Termination

You may stop using the Service and delete your account at any time from the app's Settings screen.
We may suspend or terminate accounts that breach these Terms, abuse the Service, or where required by law.
On termination, your data is deleted within 30 days, except where retention is required for legal, tax or fraud-prevention purposes.

10. Liability

To the maximum extent permitted by law, our liability for any loss or damage arising from the Service is limited to the greater of (a) the fees you paid us in the 12 months before the event giving rise to the claim, or (b) €100. We are not liable for indirect, incidental, consequential or punitive damages, or for loss of profits, oil, fuel, data, goodwill or business. Nothing in these Terms excludes or limits liability that cannot be excluded under Irish or EU consumer law.

11. Privacy

Personal data is handled in line with our Privacy Policy, which forms part of these Terms.

12. Changes to these Terms

We may update these Terms; material changes will be flagged in the app or by email at least 14 days before they take effect. Continuing to use the Service after the effective date constitutes acceptance.

13. Governing law & disputes

These Terms are governed by the laws of Ireland. Disputes will be resolved in the courts of Ireland, save that EU consumers retain the right to bring an action in the courts of their country of residence and to use the EU Online Dispute Resolution platform at ec.europa.eu/consumers/odr.
