These Terms of Service ("Terms") govern your use of the Brightwater iOS application (bundle identifier xyz.bogtsi.brightwater) and any content or features it provides (the "App"). The App is provided by an individual developer based in Israel ("we", "us", or "our"). By downloading, accessing, or using the App, you agree to these Terms. If you do not agree, do not use the App.
Subject to your compliance with these Terms, we grant you a personal, limited, non-exclusive, non-transferable, revocable license to download and use the App on Apple devices that you own or control, for your own personal, non-commercial use. This license is granted under the terms of Apple's Licensed Application End User License Agreement (EULA), which applies to your use of the App as an application obtained through the App Store; where these Terms are silent, Apple's standard EULA governs.
You may not copy, modify, reverse-engineer, decompile, sublicense, sell, rent, or otherwise exploit the App or its content except as expressly permitted by these Terms or applicable law.
Brightwater offers an optional auto-renewing subscription ("Brightwater Pro") that unlocks additional features — including unlimited tanks, full chart history with overlays, the full cycle assistant beyond week one, lighting plans for every tank, custom reminder cadences, and more photos per diary entry. Brightwater remains genuinely usable without it: your first three tanks, core logging and reminders, 60-day charts, one lighting plan, cycle week one, livestock, diary, expenses, and CSV export are free. Subscriptions and payments are handled by Apple through the App Store; we never receive or store your payment card details.
Subscription entitlements are managed through RevenueCat on our behalf. See our Privacy Policy for details on the data involved.
The App contains no advertising and no advertising SDK. If we enable advertising in a future update, this section and our Privacy Policy will be updated before it ships.
You agree not to:
The care, lighting, algae, and nitrogen-cycle content in the App is general hobbyist information, compiled from commonly accepted aquarium-keeping practice with cited sources shown in the App. It is provided for information only. It is not professional, veterinary, or scientific advice, and it is not tailored to your specific tank, water supply, equipment, plants, or animals.
Every aquarium is different. Readings you log are only as accurate as your test kit and your technique. Safe ranges, cycle timelines, lighting recommendations, and algae guidance in the App are general guidelines — we do not guarantee water quality, plant health, algae outcomes, cycle completion by any date, or the health or survival of fish, invertebrates, or other livestock. Where the evidence for a practice is anecdotal, the App says so. You are responsible for your own animals: test your water, research the species you keep, act on what you observe in the tank rather than on the App alone, and consult experienced keepers or an aquatic veterinarian when something is wrong.
Brightwater is a logbook and planner. It does not connect to, monitor, or control any aquarium equipment — no lights, heaters, filters, dosing pumps, controllers, or probes, and no Bluetooth or Wi-Fi devices. The lighting planner produces a written schedule and optional on/off reminders delivered to you; acting on them, and operating your equipment safely, is entirely up to you.
The App and all of its content — including software, design, text, graphics, and artwork — are owned by us or our licensors and are protected by intellectual-property laws. Except for the limited license in Section 1, no rights are granted to you. "Brightwater" and associated marks are our property.
The entries you create in the App — tanks, readings, maintenance history, lighting plans, cycle progress, livestock, diary notes, photos, and expenses — are stored on your device, not on a server we operate. You are responsible for keeping your own copies of anything you wish to preserve — the App's per-tank CSV export exists for that purpose and is available on every plan. Deleting the App permanently removes that data from your device, and we cannot recover it for you.
The App relies on third-party services, including Apple (App Store) and RevenueCat. Your use of those services through the App may be subject to their own terms and policies. We are not responsible for the practices of these third parties.
The App is provided "as is" and "as available", without warranties of any kind, whether express, implied, or statutory, including implied warranties of merchantability, fitness for a particular purpose, title, and non-infringement. We do not warrant that the App will be uninterrupted, error-free, or secure, that any guidance, reminder, or figure it displays will be accurate or timely, or that any defects will be corrected. You use the App at your own risk, to the maximum extent permitted by applicable law.
To the maximum extent permitted by applicable law, in no event will we be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of data, profits, goodwill, or other intangible losses — including any loss of or harm to aquarium livestock, plants, or equipment — arising out of or relating to your use of (or inability to use) the App, even if we have been advised of the possibility of such damages. To the maximum extent permitted by law, our total aggregate liability for any claim arising out of or relating to the App or these Terms will not exceed the greater of the amount you paid us for the App in the twelve (12) months preceding the claim, or ten U.S. dollars (US$10).
Some jurisdictions do not allow certain limitations, so some of the above may not apply to you; in that case, our liability is limited to the smallest extent permitted by law.
You agree to indemnify and hold us harmless from any claims, damages, liabilities, and expenses (including reasonable legal fees) arising from your misuse of the App or your violation of these Terms or of applicable law.
These Terms are between you and us only, not with Apple. Apple is not responsible for the App or its content. Apple has no obligation to provide maintenance or support for the App. In the event of any failure of the App to conform to any applicable warranty, you may notify Apple, and Apple may refund the purchase price (if any); to the maximum extent permitted by law, Apple has no other warranty obligation with respect to the App. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.
These Terms remain in effect while you use the App. We may suspend or terminate your access if you violate these Terms. You may stop using the App at any time by deleting it. Sections that by their nature should survive termination (including intellectual property, disclaimers, limitation of liability, and governing law) survive.
These Terms are governed by and construed in accordance with the laws of the State of Israel, without regard to its conflict-of-laws rules. Subject to any mandatory consumer-protection rights available to you under the law of your country of residence, you agree that the competent courts located in Israel will have exclusive jurisdiction over any dispute arising out of or relating to these Terms or the App.
We may update these Terms from time to time. When we do, we will revise the "Last updated" date above and post the new version at this URL. Your continued use of the App after changes take effect constitutes acceptance of the revised Terms. If you do not agree to the changes, stop using the App.
