Terms of Use & Medical / AI Liability Disclaimer

1. Parties, Scope & Relationship to Apple Standard EULA

Provider and Operator of the Service: Fuat Tarik İSLAM (TengrX). Postal address: İzmir, Türkiye. Support and legal contact email: hello@tengrx.com.

Your license to use the MewBite iOS application on Apple-branded devices is also subject to Apple’s standard Licensed Application End User License Agreement (“Apple Standard EULA”). In the event of any conflict between these Terms and the Apple Standard EULA, these Terms shall govern except with respect to mandatory provisions protecting Apple Inc. and its subsidiaries.

2. No Medical Advice & Healthcare Disclaimer (Critical Provision)

NOT A MEDICAL DEVICE OR HEALTHCARE PROVIDER: MewBite does not provide medical advice, clinical nutrition therapy, dietetics, psychotherapy, or healthcare services, and is not cleared, approved, or registered as a medical device by the US Food and Drug Administration (FDA), the European Medicines Agency / EU MDR Notified Bodies, or the Turkish Medicines and Medical Devices Agency (TİTCK). The Service is not intended to diagnose, treat, cure, mitigate, or prevent any disease, metabolic disorder, obesity, or eating disorder.

CONSULT A PHYSICIAN FIRST: Always consult a licensed physician or registered dietitian before starting any calorie-restricted diet, macronutrient regimen, intermittent fasting protocol, or exercise program. Never disregard professional medical advice or delay seeking medical care because of any score, chart, projection, or AI Coach response displayed in the Service. If you believe you are experiencing a medical emergency, call your local emergency services (e.g., 112 or 911) immediately.

ESTIMATED METABOLIC FORMULAS: All Basal Metabolic Rate (BMR), Total Daily Energy Expenditure (TDEE), Body Mass Index (BMI), daily calorie/macro targets, estimated energy deficit/surplus balances, and projected goal dates in the Service are mathematical approximations derived from population-level equations (such as Mifflin-St Jeor). Individual metabolism varies significantly based on genetics, hormones, thyroid function, lean mass, medications, and sleep; we make no guarantee regarding weight loss, muscle gain, or health outcomes.

3. Artificial Intelligence (AI) Estimates, Nutrition Values & Allergen Warning

LIMITATIONS OF AI VISION & TEXT PARSING: Camera food scanning (CameraFoodAIService / analyze-entry), voice/text meal logging, AI Coach (Mia, Alex, Nova), and Chef Mew recipe suggestions are generated by probabilistic artificial intelligence models. AI can misidentify a dish entirely, misjudge portion weight or plate depth, and cannot see cooking oils, butter, dressings, sauces, sugars, or recipe variations.

ALLERGEN & FOOD SAFETY DISCLAIMER: MewBite and its AI features CANNOT detect or guarantee the absence of food allergens (including peanuts, tree nuts, wheat/gluten, milk/dairy, eggs, soy, fish, shellfish, sesame, mustard, celery, lupin, or sulfites), cross-contamination, raw/undercooked ingredients, or food spoilage. If you have food allergies, celiac disease, lactose intolerance, phenylketonuria, renal disease, or insulin-dependent diabetes, you must NEVER rely on MewBite’s AI estimates or nutrition database for safety or insulin dosing; always inspect original manufacturer labels and verify ingredients directly with food preparers.

4. Intermittent Fasting Contraindications & Physical Workout Assumption of Risk

INTERMITTENT FASTING CONTRAINDICATIONS: Intermittent fasting timers are provided solely for healthy adults who choose to track self-selected eating windows. You must NOT use intermittent fasting timers or aggressive calorie-deficit settings if you belong to any of the following groups:

• Individuals who are pregnant, breastfeeding/lactating, or trying to conceive;
• Children and adolescents under the age of 18;
• Individuals with a current or past diagnosis, history, or symptoms of an eating disorder (e.g., anorexia nervosa, bulimia nervosa, binge eating disorder, orthorexia, ARFID) or who are clinically underweight;
• Individuals with Type 1 or Type 2 diabetes, reactive hypoglycemia, cardiovascular disease, low blood pressure, kidney or liver disease, gout, or gastrointestinal ulcers;
• Individuals taking prescription medications that must be taken with food or at strict intervals.

GUIDED WORKOUTS & PHYSICAL EXERCISE RISK: Guided workout plans, exercise demonstrations, set/rep targets, and burned-calorie estimates in MewBite are general fitness templates and do not account for your personal orthopedic, joint, or cardiovascular history. Physical exercise carries inherent risks of muscle strain, joint injury, fainting, or cardiac events. You voluntarily assume all risks associated with performing any exercise logged or suggested in the Service, and you agree to stop exercising immediately if you feel pain, dizziness, shortness of breath, or chest discomfort.

5. Eligibility & Age Requirements

You must be at least 13 years of age to use the Service. If you are under the age of majority in your jurisdiction (under 18 in Türkiye and most jurisdictions), you may use the Service and make in-app purchases only with the consent and supervision of your parent or legal guardian.

Calorie deficit plans, intermittent fasting timers, and AI Coach features are intended solely for adults aged 18 and older.

6. Accounts, Guest Mode, MewCoin Economy & Referral Program

Guest Mode & Cloud Accounts: You may use MewBite in Guest Mode without registering an account. Because Guest Mode stores all data locally on your device, losing your device or uninstalling the app will permanently erase your un-synced local data. Signing in with Apple or Google backs up your profile, daily goals, MewCoin ledger, and completed workout sessions to Supabase.

MewCoin & Virtual Cosmetics: “MewCoins” earned through daily/weekly challenges and virtual mascot cosmetics (coin_state / reward_ledger) are strictly non-monetary in-app gamification elements. MewCoins have no cash value, are not property or electronic money, cannot be redeemed for real currency, and cannot be sold, transferred, or refunded upon account deletion or service termination.

Referral Program Rules: Our referral program rewards users with promotional subscription time only when a genuinely invited friend becomes a qualified paid subscriber and remains subscribed past the verification window (subject to monthly reward caps and anti-fraud checks). Self-referrals, duplicate accounts, refund/cancel cycling, or automated abuse will result in rejection or revocation of referral rewards.

7. Acceptable Use Policy

When using the Service, you agree NOT to:

• Submit illegal, abusive, defamatory, sexually explicit, self-harm/eating-disorder-promoting, or privacy-infringing content to camera, voice, or AI Coach endpoints;
• Attempt prompt injection, jailbreaking, or automated scraping/flooding of our Supabase Edge Functions (analyze-entry, ai-coach, nutrition-train, claim-referral);
• Tamper with or forge MewCoin ledger requests (reward_ledger) or referral qualification tokens;
• Reverse engineer, decompile, disassemble, copy, or commercially redistribute the MewBite app binary, procedural mascot animation engine, illustrations, or editorial content;
• Misrepresent AI-generated nutrition or workout outputs as certified medical or dietetic advice.

We reserve the right to rate-limit, suspend, or terminate access to cloud or AI endpoints in cases of material or repeated violations of these rules.

8. Subscriptions (MewBite Premium), Auto-Renewal & Refunds

Pricing & Billing: Certain features of MewBite require a paid “MewBite Premium” subscription. Subscription tiers, billing intervals, prices, and any applicable free trial terms are displayed on the in-app paywall and confirmed in Apple’s StoreKit purchase sheet. Payment is charged by Apple to your Apple Account upon confirmation of purchase.

Automatic Renewal & Cancellation: Subscriptions automatically renew at the end of each billing cycle unless auto-renew is turned off at least 24 hours before the end of the current period (or free trial). Your Apple Account will be charged for renewal within 24 hours prior to the end of the current period. You can manage and cancel your subscription at any time in iOS Settings → [Your Name] → Subscriptions (or at apps.apple.com/account/subscriptions). Uninstalling the app or deleting your MewBite account inside the app does NOT cancel an active Apple subscription.

Free Trials & Restore Purchases: Any unused portion of a free trial period is forfeited when you purchase a subscription, where applicable. You may restore active entitlements on a new iOS device signed into the same Apple Account using the in-app “Restore Purchases” button.

Refunds & Right of Withdrawal: Because all in-app payments are processed exclusively by Apple, refund requests must be submitted directly to Apple via https://reportaproblem.apple.com under Apple’s Media Services Terms; we cannot issue refunds directly from Apple’s billing system. Where you consent to immediate performance of digital content, the statutory right of withdrawal under distance-selling laws (including Turkish Distance Contracts Regulation Art. 15/1-ğ and EU Consumer Rights Directive 2011/83/EU Art. 16(m)) may cease to apply once delivery begins, without prejudice to your mandatory statutory remedies for defective digital services.

9. Intellectual Property Rights

All rights, title, and interest in and to the MewBite mobile application, mewbite.tengrx.com, the “MewBite” and “TengrX” trademarks, the “Mew” companion character artwork, procedural soft-body animation engine, user interface design, source code, and editorial nutrition/fasting guides are owned by Fuat Tarik İSLAM (TengrX) or its licensors.

Subject to your compliance with these Terms, we grant you a personal, limited, non-exclusive, non-transferable, non-sublicensable, revocable license to install and use the MewBite iOS application on Apple-branded devices that you own or control, solely for your personal, non-commercial wellness use.

10. Your Content & Feedback

You retain ownership of the meal logs, food photos, voice notes, workout logs, and AI Coach prompts you input into the Service (“User Content”). You grant us a limited technical license to process your User Content solely as necessary to provide the Service to you (such as running AI analysis or syncing your cloud profile) in accordance with our Privacy Policy.

If you submit voluntary ratings, suggestions, or bug reports (including via experience_reviews or email), you grant us a royalty-free, perpetual right to use that feedback to improve the Service without obligation or compensation to you.

11. Service Availability & Modifications

We strive to keep the Service reliable and accurate, but temporary interruptions may occur due to maintenance, network conditions, or outages at third-party infrastructure providers (Apple, Supabase, OpenAI, RevenueCat). Cloud sync backs up only the specific tables described in Section 4 of our Privacy Policy and is not a guaranteed backup of your local meal diary or local photos.

We may update, modify, or discontinue features to improve security, performance, or legal compliance. If we materially remove core paid functionality during an active subscription term, we will provide reasonable advance notice and honor your statutory consumer rights.

12. Disclaimer of Warranties & Limitation of Liability

DISCLAIMER OF WARRANTIES: To the maximum extent permitted by applicable mandatory law, the Service and all AI outputs, nutritional estimates, fasting timers, and workout templates are 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 medical or nutritional purpose, accuracy, or non-infringement.

LIMITATION OF LIABILITY: To the fullest extent permitted by law, Fuat Tarik İSLAM (TengrX) and its suppliers shall not be liable for: (i) any health complication, allergic reaction, nutritional deficiency, eating-disorder relapse, physical injury, or failure to achieve weight/fitness goals arising from reliance on AI estimates, macro targets, fasting timers, or workout plans; (ii) any loss of local on-device data caused by device loss, OS resets, or app deletion; or (iii) any indirect, incidental, consequential, special, or punitive damages. Where liability cannot be lawfully excluded, our total aggregate liability to you for all claims arising out of or relating to the Service shall not exceed the total subscription fees paid by you for the Service during the twelve (12) months immediately preceding the event giving rise to the claim (or USD 50 / TRY 1,000 if no fees were paid).

MANDATORY CONSUMER EXCEPTIONS: Nothing in these Terms excludes or limits liability for willful misconduct or gross negligence (Turkish Code of Obligations Art. 115), death or personal injury caused by negligence, fraud, or any mandatory consumer rights that cannot be waived under Turkish Law No. 6502, EU/UK consumer law, or your local jurisdiction.

13. Apple App Store Mandatory Terms (Third-Party Beneficiary)

When you download the MewBite iOS application from the Apple App Store, you acknowledge and agree to the following mandatory Apple terms:

• Acknowledgement: These Terms are concluded between you and Fuat Tarik İSLAM (TengrX) only, and not with Apple Inc. (“Apple”). Fuat Tarik İSLAM (TengrX), not Apple, is solely responsible for the Licensed Application and the content thereof.
• Maintenance and Support: Apple has no obligation whatsoever to furnish any maintenance and support services with respect to the Licensed Application.
• Warranty: In the event of any failure of the Licensed Application to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any) for the Licensed Application to you; to the maximum extent permitted by applicable law, Apple will have no other warranty obligation whatsoever with respect to the Licensed Application.
• Product Claims: Fuat Tarik İSLAM (TengrX), not Apple, is responsible for addressing any claims by you or any third party relating to the Licensed Application or your possession and/or use of the Licensed Application, including: (i) product liability claims; (ii) any claim that the Licensed Application fails to conform to any applicable legal or regulatory requirement; and (iii) claims arising under consumer protection, privacy, HealthKit, or similar legislation.
• Intellectual Property Rights: In the event of any third-party claim that the Licensed Application or your possession and use of that Licensed Application infringes that third party’s intellectual property rights, Fuat Tarik İSLAM (TengrX), not Apple, will be solely responsible for the investigation, defense, settlement, and discharge of any such intellectual property infringement claim.
• Legal Compliance: You represent and warrant that (i) you are not located in a country that is subject to a U.S. Government embargo, or that has been designated by the U.S. Government as a “terrorist supporting” country; and (ii) you are not listed on any U.S. Government list of prohibited or restricted parties.
• Third-Party Beneficiary: Apple, and Apple’s subsidiaries, are third-party beneficiaries of these Terms, and upon your acceptance of these Terms, Apple will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary thereof.

14. Termination

You may terminate these Terms at any time by uninstalling the app and using the in-app “Delete Account / Start Fresh” feature to erase your cloud and local data.

We may suspend or terminate your access to cloud or AI features if you materially breach Section 7 (Acceptable Use) or compromise the security of the Service, while respecting any mandatory consumer rights applicable to your paid subscription period. Sections 2, 3, 4, 9, 12, 13, and 15 shall survive termination.

15. Governing Law & Dispute Resolution

If you have any concern or dispute, please contact us first at hello@tengrx.com; we resolve the vast majority of issues quickly and amicably.

These Terms are governed by the laws of the Republic of Türkiye, without regard to conflict-of-laws rules. Consumers residing in Türkiye may bring disputes before their local Provincial or District Consumer Arbitration Committees (Tüketici Hakem Heyetleri) within the annual monetary thresholds set under Law No. 6502 on Consumer Protection, or before the Consumer Courts (Tüketici Mahkemeleri) above those thresholds.

Consumers residing in the European Union, the United Kingdom, or other jurisdictions retain the benefit of mandatory consumer protection laws of their country of habitual residence and may bring proceedings in the courts of their place of residence. For non-consumer (commercial) disputes, the Courts and Enforcement Offices of İzmir (Central), Türkiye shall have exclusive jurisdiction.

16. Changes to Terms, Severability & Language

We may update these Terms when we add new features or when legal requirements change. The effective version date (2026-10-19) is shown at the top of this page, and material changes will be notified inside the app.

If any provision of these Terms is held invalid or unenforceable, the remaining provisions will remain in full force and effect. Our failure to enforce any right does not constitute a waiver of that right. In case of any discrepancy between the Turkish and English versions, the Turkish text shall prevail for matters governed by Turkish law, without prejudice to mandatory consumer protections in your country of residence.
