Terms of Service
Last updated: September 2026
These Terms of Service (“Terms”) govern your use of the Sugarfree mobile application and related services (together, the “App”). Sugarfree is operated by the walking puffin (“we”, “us”, “our”); you can contact us at admin@sinazucar.eu. By downloading, installing or using the App you agree to these Terms. If you do not agree, do not use the App.
Nothing in these Terms affects your mandatory rights as a consumer that cannot be waived by agreement.
1. What Sugarfree is
Sugarfree is a general wellness tool for logging sugar intake, showing a suggested daily cap and goal derived from information you enter, and tracking sugar-free days. Any caps, goals, calorie or nutrient figures are estimates produced by standard formulas from the data you provide. They are not tailored to your individual circumstances.
2. Not medical advice
Sugarfree does not provide medical, nutritional, or professional health advice, diagnosis, or treatment, and using it does not create a practitioner–patient relationship. The App is not a medical device.
Do not use Sugarfree to manage a medical condition. Always consult a qualified healthcare professional before making changes to your diet, and about any symptoms or conditions — including if you have or may have diabetes, an eating disorder, are pregnant or breastfeeding, or are caring for a child. Decisions about what you eat are yours. If you think you may have a medical emergency, contact your local emergency services.
3. Eligibility and your account
You must be at least 18 years old to use the App. The core App works locally without an account. Signing in (optional, and required for cross-device sync with a Pro subscription) means you are responsible for keeping your credentials secure and for activity under your account. Tell us promptly at admin@sinazucar.eu if you believe your account has been compromised.
4. Sugarfree Pro — subscriptions and payments
Sugarfree is free to use. “Sugarfree Pro” unlocks multi-device sync and the sugar-free streak and calendar features, offered as a monthly subscription, an annual subscription, or a one-time lifetime purchase.
- Billing. All purchases are made through and processed by the Apple App Store or Google Play under their terms. We do not take payment directly.
- Auto-renewal. Monthly and annual subscriptions renew automatically at the then-current price until cancelled. The lifetime purchase does not renew.
- Managing and cancelling. Manage or cancel a subscription in your Apple or Google account settings, at least 24 hours before the renewal date. Cancelling stops future renewals; access continues until the end of the paid period.
- Refunds. Refunds are handled by Apple or Google under their policies. We cannot issue refunds directly. This does not affect any statutory right of withdrawal you have as a consumer.
- Price changes. We may change subscription prices for future billing periods. Where required, Apple or Google will notify you and, for subscriptions, ask for your consent to continue.
- What Pro does not do. Losing Pro (for example, letting a subscription lapse) does not delete your local data. Data already synced to our backend remains readable so you can export it; new cloud writes stop.
5. Your data and backups
Sugarfree is local-first: by default your logs, profile, and history live only on your device. You are responsible for maintaining your own backups of data stored on your device (use the export option in Settings). We are not responsible for loss of locally-stored data, including loss caused by device failure, deleting the App, or operating-system behaviour.
How we handle data you sync to us is described in our Privacy Policy. You can delete your account and associated cloud data at any time — see Delete my account.
6. Acceptable use
You agree not to: use the App unlawfully or for anyone else’s data without their consent; reverse engineer, decompile, or attempt to extract source code except as permitted by law; probe, scan, overload, or disrupt the App or our backend; circumvent security, entitlement, or rate-limiting controls; resell or commercially redistribute the App; or use the App in a way that infringes others’ rights.
7. Intellectual property
The App, its design, and its content (excluding your data and third-party content) are owned by us or our licensors and are protected by intellectual-property laws. We grant you a personal, non-exclusive, non-transferable, revocable licence to use the App on devices you own or control, for your own personal use, subject to these Terms and the relevant app store’s rules.
Your data stays yours. We claim no ownership of the information you enter. You grant us only the limited licence needed to operate the App and provide the features you use (for example, storing and syncing your logs if you have Pro).
Product and nutrition information for barcodes is provided by Open Food Facts and is used under the Open Database License (ODbL).
8. Third-party services and content
The App relies on third parties, including Apple, Google, our hosting provider (Supabase, EU-hosted), our subscription-management provider (RevenueCat), and Open Food Facts. Their services are governed by their own terms, and we are not responsible for them. Barcode and nutrition data may be incomplete, out of date, or inaccurate — always check product packaging.
9. Disclaimers
To the fullest extent permitted by law, the App is provided “as is” and “as available”, without warranties of any kind, whether express or implied, including implied warranties of merchantability, satisfactory quality, fitness for a particular purpose, accuracy, and non-infringement. We do not warrant that the App will be uninterrupted, error-free, or that any estimate, figure, or calculation it produces is accurate or suitable for you.
10. Limitation of liability
Nothing in these Terms excludes or limits our liability for: death or personal injury caused by our negligence; fraud or fraudulent misrepresentation; any liability under applicable product-liability law that cannot be excluded; or any other liability that cannot be excluded or limited under applicable law, including your statutory rights as a consumer.
Subject to the paragraph above, and to the fullest extent permitted by law:
- we are not liable for any indirect, incidental, special, or consequential loss, or for loss of profits, revenue, data, goodwill, or anticipated savings, arising out of or in connection with the App or these Terms;
- we are not liable for any outcome arising from your reliance on information, estimates, caps, goals, or calculations provided by the App, or from decisions you make about your diet or health;
- we are not liable for loss of data stored locally on your device; and
- our total aggregate liability for all claims arising out of or in connection with the App or these Terms is limited to the total amount you paid for Sugarfree Pro in the 12 months before the event giving rise to the claim.
11. Changes to the App and these Terms
We may change, suspend, or discontinue features of the App. We may update these Terms; if a change is material we will give reasonable notice (for example, in the App or by email). Continuing to use the App after a change takes effect means you accept the updated Terms. If you do not accept them, stop using the App and, if you wish, cancel any subscription through the relevant app store.
12. Termination
You may stop using the App at any time and delete it. We may suspend or end your access if you materially breach these Terms or use the App in a way that risks harm to other users or to us. You can delete your account and cloud data at any time via Delete my account. Sections that by their nature should survive termination (including sections 7–10 and 13) do so.
13. Governing law and disputes
These Terms are governed by the laws of Ireland. The courts of Ireland have non-exclusive jurisdiction. If you are a consumer resident in the EU, you also benefit from any mandatory protections of the law of your country of residence, and you may bring proceedings there. The European Commission’s Online Dispute Resolution platform is available for consumer disputes.
14. Apple App Store
If you download the App from the Apple App Store: these Terms are between you and us, not Apple, and Apple is not responsible for the App or its content. Apple has no obligation to provide maintenance or support for the App. Apple is not responsible for any product warranties or for addressing any claims relating to the App (including product-liability claims, claims that the App fails to conform to a legal requirement, and claims under consumer-protection or privacy law). In the event of a third-party claim that the App infringes intellectual-property rights, we, not Apple, are responsible. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you. You confirm you are not located in a country subject to a US Government embargo or designated as “terrorist supporting”, and are not on any US Government restricted-parties list.
