These Terms of Service (“Terms”) form a binding legal agreement between you (“you” or “User”) and Bygga (“Bygga”, “we”, “us”, or “our”), the company that owns and operates the Lullu mobile application, the website at lulluapp.com, and all related software, content, and services (collectively, the “Service”). Please read these Terms carefully. By creating an account, downloading, accessing, or using the Service, you agree to these Terms. If you do not agree, you must not use the Service.
IMPORTANT. PLEASE READ. The Service is an informational tracking and journaling tool. It is not a medical device, is not intended to diagnose, treat, cure, monitor, or prevent any disease or condition, and must never be used as a substitute for professional medical advice, diagnosis, treatment, or emergency care. Sections 5 (Medical Disclaimer), 13 (Disclaimers), 14 (Limitation of Liability), 15 (Indemnification), and 17 (Binding Arbitration and Class-Action Waiver) limit our liability and affect your legal rights, including your right to bring a lawsuit in court or participate in a class action. Please review them carefully.
You must be at least 18 years old (or the age of legal majority in your jurisdiction) and able to form a legally binding contract to use the Service. The Service is intended for use by parents, legal guardians, and authorized caregivers tracking information about a child or pregnancy. The Service is not directed to or intended for use by children under 13, and children may not create accounts.
You are responsible for maintaining the confidentiality of your account credentials and for all activity that occurs under your account. You agree to provide accurate, current, and complete information at registration and to keep it up to date. You must notify us promptly of any unauthorized use of your account at hello@lulluapp.com.
Subject to your continued compliance with these Terms, Bygga grants you a limited, personal, non-exclusive, non-transferable, non-sublicensable, revocable license to download, install, and use the Service on devices you own or control, solely for your personal, non-commercial use. All rights not expressly granted are reserved by Bygga and its licensors.
You agree not to: (a) use the Service in any manner that violates applicable law; (b) reverse engineer, decompile, disassemble, or attempt to derive source code from the Service, except to the extent permitted by law; (c) interfere with, disrupt, or attempt to gain unauthorized access to the Service, our servers, or any related systems; (d) use any automated means (bots, scrapers, crawlers) to access the Service; (e) upload or transmit malware, viruses, or harmful code; (f) impersonate any person or misrepresent your relationship to a child whose data you log; (g) use the Service to harass, abuse, or harm another person; (h) resell, sublicense, or commercially exploit the Service; or (i) remove or alter any proprietary notices.
The Service allows you to log information including, without limitation, feeding, sleep, diaper, growth, milestone, medication, and allergy data, photos, notes, and pregnancy information (collectively, “User Content”). As between you and Bygga, you retain ownership of your User Content. You grant Bygga a worldwide, non-exclusive, royalty-free, transferable, sublicensable license to host, store, reproduce, modify (for technical purposes such as formatting and back-up), transmit, and display your User Content solely to operate, provide, secure, and improve the Service for you and any caregivers you have authorized.
You represent and warrant that (i) you own or have all necessary rights to your User Content, (ii) you have legal authority to log information about any child, pregnancy, or other person referenced in your User Content (as parent, legal guardian, or other person with lawful authority), and (iii) your User Content does not violate any law or third-party right. You are solely responsible for the accuracy, legality, and appropriateness of your User Content.
The Service is an informational and journaling tool only. It is not a medical device. It has not been evaluated, cleared, or approved by the U.S. Food and Drug Administration or any other regulatory authority. The Service does not provide medical, nursing, lactation, nutritional, psychological, or any other professional advice. No content in the Service (including growth charts, percentile estimates, feeding patterns, sleep summaries, milestone benchmarks, allergy logs, medication reminders, prenatal information, or any other output) is intended to diagnose, treat, cure, monitor, prevent, or manage any disease, condition, or symptom.
Always seek the advice of a qualified healthcare professional with any questions you may have regarding your child's health, growth, feeding, sleep, medication, allergies, vaccinations, development, or any pregnancy-related matter. Never disregard, delay, or modify professional medical advice because of something you read or saw in the Service.
If you believe your child or you may be experiencing a medical emergency, call 911 (or your local emergency number) immediately. Do not use the Service to request emergency assistance.
The Service may offer reminders, notifications, timers (including for feeding, sleep, and medication), and offline tracking. You acknowledge and agree that these features are provided on a best-effort basis and may fail, be delayed, be inaccurate, or not deliver at all for many reasons outside our control, including (without limitation): your device being off, locked, in low-power or do-not-disturb mode, denying notification permissions, OS-level termination of background processes, software bugs, network outages, push-notification provider failures (Apple Push Notification service, Firebase Cloud Messaging), loss of device, corrupted local storage, app updates, and offline data being lost if the app is uninstalled or device data is wiped before sync completes.
You are solely responsible for the timing, dosage, and administration of any feeding, medication, supplement, or care activity. You must not rely on the Service as the sole means of remembering or verifying any such activity. Always confirm directly with your healthcare provider, the medication label, and your own independent records.
The Service allows you to invite partners, co-parents, family members, nannies, and other caregivers (“Invited Users”) to view, contribute to, and edit information about a child. By inviting an Invited User, you represent and warrant that (a) you have the legal right and authority to share that child's information with that person, (b) you have obtained any consent required from any other parent or guardian, and (c) the Invited User has agreed to use the information only for caregiving purposes consistent with these Terms.
You acknowledge that Invited Users may add, edit, or delete data, may export information from the Service, and may continue to retain copies of any information they viewed even after their access is revoked. Bygga is not responsible for the acts or omissions of Invited Users, for disputes between co-parents or caregivers, or for any misuse of shared information by an Invited User. You are responsible for revoking access promptly when appropriate.
Certain features of the Service require a paid subscription (“Subscription”). Current pricing is $4.99 USD per month or $49.99 USD per year, billed in advance through your Apple App Store account (or other supported app store). New users may be eligible for a 7-day introductory free trial as offered by Apple; the trial converts to a paid Subscription if not cancelled at least 24 hours before the trial ends.
Subscriptions auto-renew at the then-current price for the same billing period unless you cancel at least 24 hours before the end of the current period. You can cancel anytime in your App Store account settings; cancellation takes effect at the end of the then-current billing period. Except where required by law, all payments are non-refundable, and we do not provide refunds or credits for partial periods, unused features, or failure to use the Service. Refund requests are governed by the policies of the app store through which you purchased.
We may change prices, fees, or the features included in any Subscription. Material price changes will take effect at your next renewal after we provide reasonable advance notice. Continued use after a price change constitutes acceptance.
Promotional pricing, free trials, and lifetime offers are subject to additional terms disclosed at the time of the offer and may be limited to one per household.
The Service relies on third-party services, including Apple (App Store, Sign in with Apple, In-App Purchase, push notifications), Google (Sign in with Google, push notifications, Play Store where applicable), Supabase (cloud database and authentication), and RevenueCat (subscription management), among others. Your use of those services is governed by their own terms and privacy policies, and Bygga is not responsible for them.
If you obtained the Service from the Apple App Store, you acknowledge that these Terms are between you and Bygga only, not Apple. Apple is not responsible for the Service or its content, has no obligation to provide maintenance or support, and is not responsible for addressing any claims relating to the Service. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you. You represent that (i) you are not located in a country subject to a U.S. Government embargo, and (ii) you are not on any U.S. Government list of prohibited or restricted parties.
The Service, including all software, designs, text, graphics, logos, icons, images, and the “Lullu” and “Bygga” names and marks, is owned by Bygga or its licensors and is protected by copyright, trademark, and other intellectual property laws. Nothing in these Terms transfers any intellectual property rights to you. You may not use any Bygga or Lullu marks without our prior written consent.
If you submit suggestions, ideas, feedback, or improvements to us (“Feedback”), you grant Bygga a perpetual, irrevocable, worldwide, royalty-free, sublicensable license to use, reproduce, modify, and exploit the Feedback for any purpose, with no obligation or compensation to you.
You may stop using the Service at any time and may delete your account from within the app or by emailing hello@lulluapp.com. We may suspend or terminate your access to the Service at any time, with or without notice, for any reason, including suspected violation of these Terms, suspected fraud, risk to other users, or as required by law. Upon termination, your right to use the Service ends immediately. Sections 4 (license you grant us), 5 (medical disclaimer), 10 (IP), 11 (feedback), 13 (disclaimers), 14 (limitation of liability), 15 (indemnification), 16 (governing law), 17 (arbitration), and 19 (general) survive termination.
To the maximum extent permitted by applicable law, the Service is provided “as is” and “as available” without warranties of any kind, whether express, implied, statutory, or otherwise. Bygga and its affiliates, officers, directors, employees, agents, suppliers, and licensors expressly disclaim all warranties, including without limitation warranties of merchantability, fitness for a particular purpose, title, non-infringement, accuracy, completeness, security, freedom from defects or harmful components, uninterrupted or error-free operation, and any warranties arising from course of dealing or usage of trade.
Without limiting the foregoing, Bygga makes no warranty that (a) the Service will meet your requirements; (b) the Service will be uninterrupted, timely, secure, accurate, complete, or error-free; (c) reminders, notifications, timers, or sync will deliver, deliver on time, or deliver correctly; (d) data will be retained, backed up, or recoverable; (e) any logged or derived information (including growth percentiles, feeding patterns, sleep summaries, allergy or medication logs) is accurate or appropriate for any purpose; or (f) any defects will be corrected. Any reliance on the Service is at your sole risk.
Some jurisdictions do not allow the exclusion of certain warranties; in those jurisdictions, the above exclusions apply only to the extent permitted by law.
To the maximum extent permitted by applicable law, in no event will Bygga or its affiliates, officers, directors, employees, agents, suppliers, or licensors be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenue, data, goodwill, business, opportunity, or other intangible loss, arising out of or relating to your access to, use of, or inability to access or use the Service, however caused and under any theory of liability (contract, tort including negligence, strict liability, statutory, or otherwise), even if Bygga has been advised of the possibility of such damages.
To the maximum extent permitted by applicable law, Bygga's aggregate liability for all claims arising out of or relating to the Service or these Terms will not exceed the greater of (a) the total amount you paid to Bygga for the Service in the twelve (12) months immediately preceding the event giving rise to the claim, or (b) one hundred U.S. dollars (US $100).
The limitations in this Section 14 apply to all claims, including without limitation claims arising from missed, delayed, inaccurate, or non-delivered reminders or notifications; medication, feeding, allergy, or care decisions made in reliance on the Service; data loss, data corruption, or sync failure; unauthorized access to your account; acts or omissions of Invited Users or other third parties; and any harm to you, your child, your family, or any other person.
Some jurisdictions do not allow the exclusion or limitation of incidental or consequential damages; in those jurisdictions, our liability is limited to the smallest extent permitted by law.
You agree to defend, indemnify, and hold harmless Bygga and its affiliates, officers, directors, employees, agents, suppliers, and licensors from and against any and all claims, liabilities, damages, losses, costs, and expenses (including reasonable attorneys' fees) arising out of or relating to (a) your access to or use of the Service; (b) your User Content; (c) your violation of these Terms or any law; (d) your violation of any third-party right, including any other parent, guardian, caregiver, or Invited User; (e) any decision or action you, an Invited User, or any third party takes in reliance on the Service; or (f) any harm to your child or any other person arising from your use of the Service. Bygga reserves the right to assume the exclusive defense and control of any matter for which you are required to indemnify us, and you agree to cooperate with our defense.
These Terms and any dispute arising out of or relating to them or the Service are governed by the laws of the State of California, United States, without regard to its conflict-of-laws rules. Subject to Section 17, you and Bygga submit to the exclusive jurisdiction of the state and federal courts located in California for any action not subject to arbitration. The United Nations Convention on Contracts for the International Sale of Goods does not apply.
Please read this section carefully. It affects your legal rights.
You and Bygga agree that any dispute, claim, or controversy arising out of or relating to these Terms or the Service (a “Dispute”) will be resolved by binding individual arbitrationadministered by JAMS under its applicable rules then in effect, and not in court, except that (a) you or we may bring an individual action in small-claims court for Disputes within that court's jurisdiction, and (b) either party may seek injunctive or equitable relief in court to protect intellectual property rights. The arbitration will take place in California (or remotely, where permitted), and judgment on the award may be entered in any court of competent jurisdiction.
Class-action waiver.You and Bygga agree that each may bring claims against the other only in your or its individual capacity and not as a plaintiff or class member in any purported class, collective, consolidated, or representative action. The arbitrator may not consolidate more than one person's claims and may not preside over any form of representative or class proceeding. If this class-action waiver is found unenforceable as to any claim, that claim must be brought in court, but all other claims remain subject to arbitration.
30-day opt-out. You may opt out of this arbitration agreement by emailing hello@lulluapp.comwithin 30 days of first accepting these Terms, with the subject line “Arbitration Opt-Out” and including your name, email, and a clear statement that you wish to opt out. Opting out does not affect any other provision of these Terms.
We may update these Terms from time to time. We will post the revised Terms with an updated “Last updated” date and, for material changes, will provide reasonable advance notice (such as in-app notice or email). Your continued use of the Service after the effective date constitutes acceptance of the revised Terms. If you do not agree, you must stop using the Service and may delete your account.
These Terms, together with our Privacy Policy, constitute the entire agreement between you and Bygga concerning the Service and supersede any prior agreements. If any provision is found unenforceable, the remaining provisions remain in full force. Our failure to enforce any provision is not a waiver. You may not assign or transfer these Terms or your account without our prior written consent; we may assign these Terms freely. There are no third-party beneficiaries to these Terms except as expressly stated. Notices to you may be provided through the Service or by email to the address on your account; notices to us must be sent to hello@lulluapp.com. Force majeure events excuse performance to the extent caused by events beyond a party's reasonable control.
