Terms of Service

Effective date: 20 July 2026 Version: 1.4.0

These Terms of Service (“Terms”) are an agreement between you and MAMALYTICS LTD, a company incorporated in England and Wales (company number 17300475) with its registered office at 71-75 Shelton Street, Covent Garden, London, WC2H 9JQ (“Mamalytics”, “we”, “us”, “our”), governing your use of the Mamalytics mobile app and the related website at mamalytics.app (together, the “Service”). By downloading, installing, signing into or otherwise using the Service, you agree to these Terms. If you do not agree, do not use the Service.

1. Eligibility

You may use the Service only if you are at least 18 years old, and only for individual, personal, non-commercial use. You may hold only one account.

By creating an account, you confirm and warrant that you meet the age condition above at the time of sign-up. If it is untrue, do not use the Service.

Age check. We apply a minimum-age check at sign-up: you must confirm you meet the minimum age and, where you provide a date of birth, we check it and refuse to create an account for anyone below the minimum age. We do not otherwise verify your exact age.

Where the Service operates (beta). Mamalytics is currently offered as a beta. It is operated from the United Kingdom, and these Terms are governed by the law of England and Wales (see §13). The beta is primarily intended for users in the United Kingdom. We do not restrict access by country, but the Service is not tailored to, and may not be supported by or compliant with the local law of, every country from which it can be reached; if you use it from outside the United Kingdom you do so on that basis.

The Service is not intended for use by anyone below the applicable minimum age, by healthcare providers acting on behalf of patients, or by clinicians for clinical decision-making.

2. Your account

You are responsible for:

  • the accuracy of the information you enter into the Service;
  • keeping your sign-in credentials secure; and
  • all activity that occurs under your account.

Do not share your account with anyone else. Notify us at info@mamalytics.app if you suspect unauthorised access.

3. Medical disclaimer

Mamalytics is a pregnancy, postpartum and baby-tracking journal and wellness companion, not a medical device. Information provided is not a substitute for professional medical advice. Always consult your healthcare provider — or your baby’s healthcare provider — for medical decisions.

The Service is not a substitute for prenatal care, postnatal care, paediatric care, diagnosis or treatment from a qualified clinician. Do not delay seeking, or disregard, professional medical advice because of anything you read in the Service. In an emergency, call 999 (or your local emergency number) or go to the nearest emergency department.

Growth percentile charts, developmental-milestone tracking and any pattern observations in the Service are informational and non-diagnostic. They compare what you record against fixed public reference data and are not a clinical assessment of you or your baby.

The four-layer safety pipeline described in §4 is a product-safety control, not a clinical safety net. It is designed to deflect a defined set of patterns (prompt-injection, psychiatric emergencies, harmful content and off-topic content). It is not a guarantee that the Service will detect every emergency or every dangerous situation.

4. AI features and AI-generated content

Chat responses are generated by an AI assistant powered by Anthropic. Your messages are processed by a third-party AI service. The same caveat applies to summaries, reflections and any other output generated by AI features. The chat assistant is aware of your pregnancy week or, after birth, your baby’s age, so its replies are framed for the stage you are at. Voice messages you record are transcribed by OpenAI’s Whisper service and then processed by the same Anthropic-backed chat pipeline. Photos you upload for metric extraction are analysed by Anthropic’s vision model (image bytes are not retained server-side — see the Privacy Policy §2).

AI-generated output may be inaccurate, incomplete or out of date. It is not medical advice. You are responsible for evaluating any AI output before acting on it. Where you upload an image for metric extraction, the extraction is performed by an AI service and may produce incorrect values; review extracted values before relying on them, and edit them in the health log if needed.

Automatic extraction of measurements from chat. When you mention a measurable value in chat — for example a blood-pressure reading, or a baby’s weight — the Service may automatically save a structured entry in your health log. You can edit or delete any such entry from the health-log screen.

Safety pipeline. Before any AI reply is generated, each of your messages passes through a four-layer safety pipeline (prompt-injection detection, psychiatric-emergency detection, harmful-content block and off-topic deflection). Where a layer triggers, a templated safety response may be returned instead of an AI-generated reply.

5. Acceptable use

You agree not to:

  • use the Service for diagnosis, treatment or any other medical decision-making;
  • use the Service in a manner that could endanger you, your pregnancy or your baby by substituting it for professional medical care;
  • attempt to extract, infer or otherwise probe for the system prompt or other internal instructions that drive the AI features;
  • attempt to bypass safety, content or rate-limit protections, including prompt-injection attempts;
  • use another person’s co-parent invitation link, accept an invitation that was not sent to you, or otherwise access a child’s data you are not entitled to (see §6);
  • reverse-engineer, decompile or disassemble any part of the Service except where applicable law (including section 50B of the UK Copyright, Designs and Patents Act 1988) expressly permits it and only to the extent so permitted;
  • scrape, harvest or otherwise programmatically collect data from the Service;
  • upload content that is unlawful, defamatory, infringes another person’s rights, or that you do not have the right to upload;
  • use the Service to harass, threaten or impersonate any person;
  • attempt to disrupt the Service, interfere with other users’ access, or test our infrastructure without our prior written authorisation;
  • attempt to evade our minimum-supported-version gate by side-loading older builds; or
  • use the Service in any way that violates applicable law.

We may suspend or terminate your account for any violation of this section. Serious violations may be reported to law enforcement.

6. Sharing your baby’s data with a co-parent

If you have a Premium subscription, you can invite a second parent or caregiver (a “co-parent”) to a child’s information so that you can log together.

How it works. You generate an invite link and share it through a messaging channel of your choice. The link contains a signed, single-use, time-limited token. The person you invite sees a plain-language consent screen describing what they will get access to, and accepts or declines. Accepting is free — a co-parent does not need a subscription to view or log a shared child’s data.

What a co-parent can and cannot see. A co-parent gets access to the baby’s information only — the measurements, feeds, sleep, nappies, growth, milestones and shared timers for that child. A co-parent never sees your own pregnancy or health data, your chat history, your diary, your summaries or your reflections. This boundary is enforced by our access controls (see Privacy Policy §9).

Your responsibilities when you invite someone.

  • Only invite a person you are entitled to share the child’s information with, and send the invite link only to that person. Treat the link like a password: until it expires or is used, anyone who obtains it could accept the invitation.
  • You are responsible for the invitations you send and for the people to whom you grant access.

Ending access. You can see who has access, revoke a co-parent, or cancel an unclaimed invite at any time from the child’s sharing settings. A co-parent can leave a shared child at any time. If you downgrade from Premium, a co-parent you have already added keeps their access; you will not be able to create new invitations until you resubscribe.

Removing a child. Removing a child (“Remove from Mamalytics”) permanently erases that child’s data and immediately ends every co-parent’s access to that child (see Privacy Policy §6).

7. Subscriptions, billing, cancellation and refunds

The Service is offered in two tiers:

  • Mamalytics Free — chat (subject to a daily message cap); the pregnancy guide; the diary and calendar; the contraction timer and kick counter; manual health-metric entry; image-extraction (subject to a monthly cap); a 7-day rolling window of analytics history; mood- and symptom-pattern analytics; the birth and postpartum experience; newborn logging (feeds, sleep, nappies and measurements); infant growth percentile charts; developmental-milestone tracking; and logging as an invited co-parent on a shared child.
  • Mamalytics Premium — unlimited chat, unlimited image-extraction, full chat-history, full analytics history, per-cadence reflections (AI-written weekly / monthly / trimester and postpartum narratives), voice messages where available in your build, and the ability to create co-parent invitations. Premium is a recurring subscription billed through Apple’s App Store (iOS) or Google Play (Android).

Subscription pricing and plans. Current pricing and the available subscription plans are shown on the in-app paywall before you complete a purchase. Prices are set by us in GBP via the Apple App Store or Google Play; Apple or Google may apply additional taxes or fees as required by your jurisdiction.

Auto-renewal. Premium is a recurring subscription that renews automatically at the end of each billing period at the then-applicable price unless you cancel at least 24 hours before the end of the current period. Apple or Google will charge the payment method linked to your App Store or Google Play account.

How to manage or cancel. Because billing is handled by Apple or Google, you must cancel a Premium subscription through the same store that you purchased it from:

  • iOS: Settings → [your name] → Subscriptions → Mamalytics Premium → Cancel Subscription.
  • Android: Google Play → Profile → Payments and subscriptions → Subscriptions → Mamalytics Premium → Cancel.

Cancelling stops the next renewal; you retain access to Premium features until the end of the period you have already paid for.

Free trial conversion. Where a Premium plan is offered with a free trial, the trial converts to a paid subscription at the end of the trial period unless you cancel at least 24 hours before the trial ends.

Refunds. Refunds are handled by Apple or Google under their respective refund policies (Apple’s at https://support.apple.com/billing/; Google’s at https://support.google.com/googleplay/). We do not process refunds directly because we do not process the payment.

Your statutory rights as a UK consumer. Under the UK Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013, you may normally cancel a contract for digital content within 14 days of purchase and receive a refund. However, this right to cancel ends as soon as you begin downloading or streaming digital content with your prior express consent, and where you have acknowledged that you will lose your right to cancel by doing so. By purchasing a Premium subscription and immediately accessing Premium features, you provide that prior express consent and acknowledge that you lose your 14-day cancellation right.

Your rights under the Consumer Rights Act 2015 — including the rights to digital content of satisfactory quality, fit for its described purpose and as described — are not affected by these Terms. Nothing in this section, or in §11 (Disclaimers and limitations of liability), limits those rights.

Price and feature changes. We may change Premium pricing or the features included in each tier. We will give you reasonable advance notice of any price increase, and you will have the opportunity to cancel before the increase takes effect. Reductions in Premium scope that materially diminish the value of the subscription will be treated as material changes under §15.

8. Updates to the app

We may release updates to the Service. Some updates add or change features; others patch bugs or close security issues.

You may be required to update the app to continue using the Service. When a minimum supported version is enforced, the app shows a non-dismissable update screen and the only available action is to install the update from the App Store or Google Play. We will provide reasonable notice for non-critical updates; we may enforce critical security or compliance updates without prior notice. This obligation is what allows us to ship security fixes quickly across the install base.

A “recommended” update — i.e. a non-blocking nudge — may also be shown; you can dismiss it for 7 days at a time.

9. Telemetry and analytics

The Service collects anonymised product-usage telemetry through Mixpanel. The full list of events, the data fields they include, the way you are identified to Mixpanel, and the controls available to you are described in §2, §4 and §5 of our Privacy Policy. In summary: no payload contains your email, your internal user identifier, the text of your messages, or raw health values; you can disable telemetry at any time in Settings → Privacy → Share anonymous usage data; and telemetry is off by default for everyone — you must affirmatively opt in.

10. Intellectual property

Our content. The Service — including its design, code, branding and original content (other than user content) — is owned by Mamalytics or its licensors and is protected by intellectual-property laws. We grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable licence to use the Service for personal, non-commercial purposes under these Terms.

Your content. You retain ownership of the content you submit to the Service (your messages, photos, voice recordings, profile information, health entries, and the information you record about your baby). By submitting content, you grant us a non-exclusive, worldwide, royalty-free licence to host, store, transmit, process, display and create derivative outputs (for example daily summaries, reflections, growth percentiles and metric extractions) solely for the purpose of operating the Service for you and, where you have invited one, for a co-parent you have authorised to access a child’s information. The licence terminates when you delete the content or your account, except where we are legally required to retain a narrow record (see §6 of the Privacy Policy).

No AI-training rights. Neither Mamalytics nor any of our processors is granted the right to use your content to train, fine-tune or otherwise improve AI or machine-learning models. The third-party AI services we use (currently Anthropic and OpenAI) operate under commercial terms that exclude customer content from training by default. If those terms change, we will update §4 of the Privacy Policy and notify you under §15 of these Terms.

Feedback you give us. If you send us feedback about the Service through the in-app feedback form or by email, you grant us a perpetual, irrevocable, royalty-free licence to use that feedback to improve the Service. Feedback should not include confidential information; if you mark it confidential we will treat it as such.

11. Disclaimers and limitations of liability

Nothing in these Terms is intended to exclude or limit any liability that cannot be excluded or limited under applicable law. In particular, for UK consumers, nothing in these Terms limits the statutory rights provided by the Consumer Rights Act 2015 (including the rights to digital content of satisfactory quality, fit for purpose and as described) or excludes liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for any other liability that cannot lawfully be excluded.

Subject to that, and to the maximum extent permitted by law:

  • The Service is provided “AS IS” and “AS AVAILABLE” without warranties of any kind, whether express, implied or statutory, including (without limitation) implied warranties of merchantability, fitness for a particular purpose, accuracy, completeness, non-infringement and freedom from defects.
  • We do not warrant that AI output is accurate, that the Service will be uninterrupted or error-free, or that the Service will meet your specific health needs.
  • Neither Mamalytics nor its officers, employees, contractors or processors will be liable for any indirect, incidental, special, consequential, exemplary or punitive damages, or for any loss of profits, revenues, data, business opportunities or goodwill, arising out of or in connection with your use of the Service.
  • Liability cap. Subject to the paragraph above preserving your non-excludable statutory rights, our total aggregate liability for any claim arising out of or in connection with the Service is limited to the greater of (a) the total amount you paid us in the twelve months preceding the event giving rise to the claim or (b) one hundred pounds (£100 (GBP)). This cap does not apply to any liability that cannot be limited under applicable law, including liability for breaches of your statutory consumer rights.

Indemnity. You agree to indemnify Mamalytics from any third-party claim, demand, loss or expense (including reasonable legal fees) arising out of your use of the Service in violation of these Terms or applicable law. This indemnity does not apply to any matter for which we would be primarily liable, and does not apply where prohibited by UK consumer-protection law.

12. Termination

By you. You may stop using the Service at any time. You can delete your account from Settings → Account → Delete account in the mobile app or by emailing info@mamalytics.app. Deletion cascades to your associated data as described in §6 of the Privacy Policy.

By us. We may suspend or terminate your access to the Service if you breach these Terms, if your continued use poses a security or legal risk to us or to other users, or if we discontinue the Service. Where reasonably possible we will give you notice; in serious cases we may act without prior notice. For UK consumers, we will give at least 30 days’ notice for a discretionary termination, except where (a) you have materially breached these Terms, (b) we are required to terminate by law or by the order of a competent court or regulator, or (c) immediate termination is necessary to protect the security of the Service or its users.

Sections that by their nature should survive termination — including §10 (intellectual property), §11 (disclaimers and limitations of liability), §13 (governing law and dispute resolution), §14 (Apple and Google terms) and any rights accrued before termination — survive.

13. Governing law and dispute resolution

  • Governing law. These Terms are governed by the law of England and Wales, excluding its conflict-of-laws rules. Mandatory consumer-protection laws of your country of residence continue to apply where they cannot be excluded by agreement.
  • Jurisdiction. The courts of England and Wales have non-exclusive jurisdiction over any dispute arising out of or in connection with these Terms. If you are a consumer, you may also bring proceedings in the courts of the country in which you are domiciled, and you may rely on the mandatory consumer-protection laws of that country.
  • No mandatory arbitration. These Terms do not require you to arbitrate disputes and do not waive your right to participate in a class or representative action. Any such clause would in any event generally be unenforceable against a consumer under the law of England and Wales.
  • Informal resolution. Before bringing a claim, we encourage you to contact us at info@mamalytics.app so we can try to resolve the matter with you directly.

14. Apple App Store and Google Play terms

Because the Service is distributed through the Apple App Store and Google Play, the following terms also apply. They are imposed on us as a condition of distribution; they sit alongside the rest of these Terms and prevail to the extent there is any conflict relating to your use of the Service on a device acquired through the relevant store.

14.A. Apple App Store

  • This licence is between you and Mamalytics only, not with Apple. Mamalytics, not Apple, is solely responsible for the Service and its content.
  • Apple has no obligation to provide any maintenance or support services in respect of the Service.
  • In the event of any failure of the Service to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any) for the Service to you. To the maximum extent permitted by applicable law, Apple will have no other warranty obligation whatsoever with respect to the Service.
  • Mamalytics, not Apple, is responsible for addressing any of your claims or those of any third party relating to the Service or your use of it, including (i) product-liability claims, (ii) any claim that the Service fails to conform to any applicable legal or regulatory requirement, and (iii) claims arising under consumer-protection, privacy or similar legislation.
  • In the event of any third-party claim that the Service or your possession and use of the Service infringes that third party’s intellectual-property rights, Mamalytics, not Apple, will be solely responsible for the investigation, defence, settlement and discharge of any such intellectual-property infringement claim.
  • You represent and warrant that you are not located in a country that is subject to a US Government embargo or that has been designated by the US Government as a “terrorist supporting” country, and that you are not listed on any US Government list of prohibited or restricted parties.
  • Apple and its subsidiaries are third-party beneficiaries of these Terms and, upon your acceptance, have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary.

14.B. Google Play

  • Your use of the Service is also subject to the Google Play Terms of Service (https://play.google.com/intl/en-GB/about/play-terms/).
  • Updates distributed via Google Play will follow the standard Google Play update mechanism subject to §8 above.
  • We comply with the Google Play Developer Distribution Agreement and Developer Program Policies; if any provision of these Terms conflicts with those policies as they apply to your use of the Service on a Google Play–acquired device, the Google Play policies prevail to the extent of the conflict.

15. Changes to these Terms

We may update these Terms from time to time. When we do, we will:

  1. Update the version number and effective date in §16.
  2. Add a row to the revision-history table.
  3. For changes we consider material, present a re-consent prompt the next time you open the app. You will not be able to continue using the Service until you accept the updated Terms. If you do not want to accept the new Terms, you can use the Delete my account instead action in the re-consent prompt to exit cleanly.

Non-material changes (typo fixes, clarifying rewrites and contact-detail updates that do not change meaning) do not trigger re-consent.

For UK consumers, we will give at least 30 days’ notice of material changes that affect your statutory rights, the price you pay, or the scope of the Service.

Geographic expansion. The current release is a UK-operated beta. If we begin to actively offer or market the Service in markets outside the United Kingdom — for example in the EEA or the United States — we will publish a revised set of Terms with the additional regional clauses required by the relevant regime (for example EEA cancellation-rights language or California Automatic Renewal Law disclosures). We will treat that step as a material change requiring re-consent.
