Terms of Use

1. About Us

My Tiny Letter ("we", "us", "our") is a trading name of My Tiny Letter, registered address in the United Kingdom. We operate the My Tiny Letter mobile application (the "App") and all associated websites, APIs, and services (collectively, the "Services").

Our registered office and principal place of business is in the United Kingdom. While our Services are available internationally, our primary regulatory framework is that of England and Wales, supplemented by applicable regional requirements described in Section 11 (Privacy & Data Protection).

2. Definitions

• "Account" : your registered profile on the Services, protected by your credentials.
• "AI-Generated Content" : audio narrations (Memory Stories), rendered artwork (Artistic Prints), and sung MP3s (Lullaby Creator) produced by automated AI systems operating on your instructions.
• "Contribution" : a message, letter, or voice recording submitted by a third party (family member, friend) via a share link you create.
• "Memory" : any voice recording, video, photograph, scan, or written note you upload or create within the App.
• "Points" : the in-app credit currency you purchase or receive as part of our service, redeemable for AI generation features.
• "Sensitive Data" : personal data revealing or relating to health, pregnancy, or a child, as defined under applicable data protection law.
• "User Content" : all Memories, Contributions, personal notes, and other material you submit through the Services.

3. Acceptance of Terms

By downloading the App, creating an Account, or otherwise accessing the Services, you confirm that you have read, understood, and agree to be bound by these Terms of Use and our Privacy Policy. If you do not agree, you must not use the Services.

If you are using the Services on behalf of a business, organisation, or other legal entity, you represent that you have the authority to bind that entity to these terms. In that case, "you" and "your" refer to that entity.

4. Eligibility and Account Registration

4.1 Age Requirement

You must be at least 18 years of age to create an Account or use the Services. By using the Services you confirm that you are 18 or over. We do not knowingly collect personal data from anyone under 18. If we discover that an Account belongs to someone under 18 we will terminate it and delete their data without prior notice.

The Services are designed for expectant and new parents. The data you provide about your pregnancy and your child relates to you as an adult user; not to the child as an account holder.

4.2 Account Security

You are responsible for maintaining the confidentiality of your login credentials and for all activity that occurs under your Account. You must notify us immediately at contact@mytinyletter.com if you suspect any unauthorised access to or use of your Account. We are not liable for any loss or damage arising from your failure to comply with this obligation.

4.3 Account Accuracy

You agree to provide accurate, current, and complete information when registering and to keep that information updated. Providing false information is grounds for immediate Account termination.

4.4 One Account Per Person

Each person may maintain only one Account. Creating multiple Accounts to circumvent restrictions, abuse our Points system, or evade a previous termination is prohibited.

5. Description of Services

5.1 Core Features

My Tiny Letter provides the following core features, which may evolve over time:

• Memories : capture and store voice recordings, videos, photographs, ultrasound scans, and written notes from your pregnancy journey.
• Growth Tracking : log and track pregnancy milestones, bump measurements, and weekly development stages.
• TinyLetters : weekly curated letters delivered to you throughout your pregnancy.
• AI Studio : three AI-powered keepsake generators: Memory Stories (narrated audio), Artistic Prints (rendered artwork), and Lullaby Creator (sung MP3).
• Sharing : create time-limited, revocable share links so family and friends can view selected content or contribute their own messages.
• Profile : manage your personal and pregnancy details, points balance, and generated keepsakes.

5.2 AI Studio

The AI Studio features use automated artificial intelligence systems to process your personal instructions and generate creative content. These features operate on credits ("Points") see Section 6. The quality, accuracy, and content of AI-generated outputs may vary and cannot be guaranteed. See Section 8 for full terms relating to AI-Generated Content.

5.3 Service Availability

We will use commercially reasonable efforts to make the Services available 24 hours a day, 7 days a week. However, we do not guarantee uninterrupted or error-free access. We may suspend, modify, or discontinue any part of the Services at any time, with or without notice, for maintenance, legal compliance, or business reasons. Where practicable, we will give you advance notice of significant planned interruptions.

5.4 Beta Features

We may make certain features available as "beta" or "preview." These are provided as-is, without any warranties, and may be discontinued or changed at any time.

6. Points, Purchases, and Refund Policy

6.1 What Points Are

Points are a virtual currency used exclusively within the Services to activate AI generation features. They have no monetary value, cannot be transferred between accounts, cannot be redeemed for cash, and expire upon Account termination unless required otherwise by applicable consumer law.

Current Point Costs

• Memory Story (AI narrated audio): 10 Points
• Artistic Print (AI rendered artwork): 5 Points
• Lullaby Creator (AI generated MP3): 10 Points

Point costs are subject to change. We will notify you of any changes before they take effect.

6.2 Purchasing Points

Points are purchased through the App using in-app purchase mechanisms provided by Apple (App Store) or Google (Google Play), or directly through our payment processor (Stripe). All transactions are subject to the terms and conditions of the relevant payment platform, as well as these Terms.

Prices are displayed in your local currency where possible. Applicable taxes (including VAT) will be added where required by law.

6.3 Automatic Point Refunds on Generation Failure

Automatic refunds are issued in the following circumstances:

• Memory Story: generation fails after exhausting all delivery attempts (dead-letter queue reached).
• Artistic Print: rendering fails after exhausting all delivery attempts.
• Lullaby Creator: AI generation fails after exhausting all delivery attempts, including where the audio output falls outside acceptable duration parameters after two generation attempts.

Points are not automatically refunded where generation fails due to content policy violations or user error (for example, selecting fewer memories than required). However, you may contact us at contact@mytinyletter.com to discuss your circumstances.

6.4 Consumer Cancellation Rights (UK and EU)

United Kingdom: Under the Consumer Rights Act 2015 and related regulations, if you purchase digital content or services, you have the right to a refund if what we supply is not of satisfactory quality, not fit for purpose, or not as described.

European Union / EEA: Under the Consumer Rights Directive (2011/83/EU), you ordinarily have a 14-day right of withdrawal from digital content purchases. However, by expressly requesting that AI generation begins immediately and acknowledging that this waives your withdrawal right once performance is complete, you consent to forfeiting the 14-day cancellation right for that specific generation. You will be clearly informed of this at the point of purchase within the App.

Points that have not been used in AI generation remain cancellable within 14 days of purchase (for EU/EEA consumers). To exercise this right, contact us at contact@mytinyletter.com.

6.5 No General Cash Refund

Except as required by applicable consumer law or as described in Sections 6.3 and 6.4, Points purchases are non-refundable. We are not required to provide a cash refund for unused Points, including on Account termination by either party.

6.6 Fraudulent Transactions

If we identify fraudulent, abusive, or unauthorised Point acquisition, including charge-backs, use of stolen payment methods, or exploiting technical errors. We reserve the right to reverse Points balances, suspend Accounts, and pursue recovery through appropriate legal channels.

7. Your Content

7.1 You Own Your Memories

You retain full ownership of all User Content you upload to the Services. Your voice recordings, photographs, videos, written notes, and scan images. We do not claim any ownership over your personal memories.

7.2 Licence You Grant Us

To operate the Services, you grant us a limited, non-exclusive, worldwide, royalty-free, sublicensable licence to:

• Store, transmit, encrypt, and back up your User Content to provide the Services;
• Process your User Content through AI systems solely to generate keepsakes you have requested;
• Display your User Content to recipients of share links you have created;
• Create, store, and serve AI-Generated Content derived from your instructions.

This licence is strictly limited to providing the Services to you. We will never use your personal memories, recordings, or photographs to train AI models, share them with third parties for commercial purposes, or make them available to other users without your explicit consent.

7.3 Your Representations

By submitting User Content, you represent and warrant that:

• You own or have the necessary rights to submit the content;
• The content does not infringe the intellectual property, privacy, or other rights of any third party;
• You have obtained consent from any identifiable third parties (other than your unborn or infant child) whose voice, image, or likeness appears in recordings or photographs;
• The content complies with all applicable laws in your jurisdiction.

7.4 Content Standards

User Content must not:

• Contain illegal, obscene, defamatory, threatening, harassing, abusive, or hateful material;
• Infringe any third-party intellectual property rights;
• Contain viruses, malware, or other harmful code;
• Impersonate any person or entity;
• Contain unsolicited commercial communications.

7.5 Our Right to Remove Content

We reserve the right (but have no obligation) to review, reject, or remove any User Content that we determine in our sole discretion violates these Terms or any applicable law. We will endeavour to notify you before removing content unless doing so would create legal risk or is not practicable.

7.6 Data Portability and Deletion

You may export your Memories and delete your Account at any time through the App's Profile settings. Upon Account deletion, we will delete your personal data in accordance with our Privacy Policy and applicable data protection law.

8. AI-Generated Content

8.1 How AI Generation Works

Our AI Studio features use large language models (Azure OpenAI GPT), text-to-speech systems (Azure Neural TTS), music generation models (ACE-Step v1.5 for Lullaby Creator), and image rendering pipelines (Puppeteer/HTML canvas for Artistic Prints). These systems produce outputs based on your instructions, selected memories, and chosen parameters.

8.2 No Guarantee of Output Quality

AI generation is inherently probabilistic. We cannot guarantee that AI-Generated Content will meet your expectations in terms of accuracy, emotional tone, artistic quality, length, or fidelity to the source material you provided. Where AI output falls outside technical parameters (for example, audio duration outside the target window), we will attempt regeneration automatically and refund your Points if the issue persists (see Section 6.3).

8.3 Content Moderation

All free-text inputs (such as personal notes for Lullaby Creator) are subject to automated content moderation before generation begins. Inputs containing prompt-injection attempts, hate speech, or other policy-violating material will be rejected with a 422 error and no Points will be debited. AI generation systems will not be used to produce content that is illegal, hateful, sexually explicit, or otherwise harmful.

8.4 Intellectual Property in AI Output

AI-Generated Content produced from your instructions and your personal memories is made available to you for your personal, non-commercial use. To the extent that AI-Generated Content is capable of attracting copyright protection, we assign any such rights to you, subject to these Terms.

You may not use AI-Generated Content to train other AI or machine learning systems, or commercially exploit AI-Generated Content in ways that exceed personal use without our prior written consent.

We retain the right to the underlying AI models, pipelines, templates, font assets, prompt engineering, and software infrastructure used to produce the content.

8.5 EU AI Act Transparency (Applicable from 2 August 2026)

In compliance with the EU Artificial Intelligence Act (Regulation (EU) 2024/1689), we disclose that:

• All AI-Generated Content produced by My Tiny Letter is labelled as AI-generated within the App;
• Our systems do not engage in prohibited AI practices under Article 5 of the EU AI Act;
• Where AI generation interacts with emotion detection or biometric categorisation, we will update these disclosures accordingly;
• You have the right to receive a meaningful explanation of any output and to contest decisions made on the basis of AI processing.

8.6 AI Does Not Replace Professional Advice

Memory Stories and other AI-Generated Content are creative keepsakes only. Nothing in any AI output constitutes medical advice about your pregnancy, your child's health, or any other matter. Always consult qualified healthcare professionals for medical decisions.

9. Sharing Features and Contributions

9.1 Share Links

The Services allow you to create time-limited, revocable links that give named or anonymous third parties ("Recipients") access to content you specify. You control exactly which content is shared and for how long. You can revoke any share link at any time through the App.

By creating a share link, you accept sole responsibility for who receives it and what they can access. We cannot control how Recipients use or store the content they view via your link.

9.2 Contributions from Third Parties

Share links can be configured to allow Recipients to submit Contributions, written messages, letters, or other content. By sending a Contribution, the Contributor:

• Represents that they have the right to submit the content;
• Grants you a licence to use their Contribution within the Services and in any AI-Generated Content you request;
• Agrees that their Contribution will be stored and processed on the same security basis as your other data.

9.3 No Responsibility for Third-Party Content

We are not responsible for Contributions submitted by third parties. If you receive a Contribution that is offensive, illegal, or otherwise objectionable, you may delete it through the App and report it to us at contact@mytinyletter.com.

10. Health and Pregnancy Data

10.1 Special Category Data

Information relating to your pregnancy, health, and the health of your baby constitutes "special category" or "sensitive" personal data under UK and EU data protection law (specifically, health data under Article 9 of UK GDPR / EU GDPR). We take the protection of this data extremely seriously.

10.2 How We Protect Sensitive Data

• Encryption at rest: All Memories, including voice recordings, photographs, and written notes, are encrypted using AES-256-GCM at the application layer before being stored in cloud storage. Each Memory has its own unique data encryption key (DEK), itself wrapped by a master key in Azure Key Vault.
• Encryption in transit: All data transferred between the App, our APIs, and storage services uses TLS 1.2 or higher.
• Access controls: Access to your data is strictly role-based. Our AI processing systems can decrypt your data only for the specific purpose of generating content you have requested, and only using time-limited, capability-scoped credentials.
• No sale of health data: We will never sell, rent, or license your pregnancy or health data to any third party, for any purpose, at any price.
• Staff training: All personnel with access to user data are trained on data protection obligations.

10.3 Baby's Information

Information you provide about your unborn or infant child (such as their name and expected due date) is processed as part of your personal data for the purpose of personalising the Services for you. This information belongs to your Account and is protected by the same security measures described above. We treat this information with particular care given its sensitive nature.

We are not the data controller in respect of the child; you, as the Account holder, control this data. Should your child, on reaching adulthood, wish to exercise rights over their data, please contact us at contact@mytinyletter.com.

11. Privacy and Data Protection

Your use of the Services is subject to our Privacy Policy, which is incorporated into these Terms by reference. The Privacy Policy explains what personal data we collect, how we use it, the legal bases for processing, your rights, data retention periods, international data transfers, and how to contact our Data Protection Officer.

11.1 UK GDPR and Data Protection Act 2018

We are registered as a data controller in the United Kingdom. Our processing of your personal data is governed primarily by the UK General Data Protection Regulation (UK GDPR) and the Data Protection Act 2018. Our lawful bases for processing include: performance of contract (providing the Services), your explicit consent (for special category health/pregnancy data), and legitimate interests (service security and fraud prevention).

11.2 EU General Data Protection Regulation (GDPR)

For users located in the European Union or the European Economic Area, we comply with EU GDPR (Regulation (EU) 2016/679). Where we transfer personal data from the EU to the UK, we rely on the UK adequacy decision adopted by the European Commission. For transfers to other third countries, we rely on appropriate safeguards including Standard Contractual Clauses.

EU users have the right to: access their data, rectify inaccurate data, erase their data ("right to be forgotten"), restrict or object to processing, receive their data in a portable format, and lodge a complaint with a supervisory authority. See our Privacy Policy for how to exercise these rights.

11.3 Nigeria Data Protection Act 2023 (NDPA)

For users located in Nigeria, we comply with the Nigeria Data Protection Act 2023 (NDPA) and the Nigeria Data Protection Regulation (NDPR) issued by the Nigeria Data Protection Commission (NDPC). Nigerian users have the right to: consent to the collection and use of their personal data, withdraw consent at any time, access their personal data, rectify inaccurate data, delete their data, object to processing, and lodge a complaint with the NDPC.

We process personal data of Nigerian users on the lawful basis of consent and performance of contract. Where required, we implement appropriate cross-border data transfer mechanisms in accordance with NDPA Part VI.

11.4 United States: California Privacy Rights (CCPA/CPRA)

For California residents, we comply with the California Consumer Privacy Act (CCPA) as amended by the California Privacy Rights Act (CPRA). California residents have the right to know what personal information we collect and how it is used, to request deletion, to opt out of any sale or sharing of personal information (we do not sell personal information), and to non-discrimination for exercising these rights. To exercise CCPA/CPRA rights, contact us at contact@mytinyletter.com.

11.5 Data Location

Our primary data processing infrastructure is located in the United Kingdom (UK South region) and the European Economic Area, operated by Microsoft Azure. Certain AI processing services (Azure OpenAI) operate from the United States (East US 2).
