Who these terms apply to

Leaf IA, Bucharest 030881, Romania provides One Little Line as a personal memory-keeping service. By using the app, you agree to these terms. If you do not agree, do not use the service.

Who can use One Little Line

You must be at least 18 years old, or the age of majority where you live, to create an account or use the app. One Little Line is made for parents, guardians, and other adults who keep memories about a child. It is not intended to be used by children, and we do not knowingly collect personal information directly from children. If you believe a child is using the app, contact us at hello@onelittleline.com and we will close that account.

Using the app

The app is designed for personal or household use. You may use it to keep family memories for yourself and your household. You must use it lawfully and must not misuse the service, interfere with it, or try to access data that is not yours.

Accounts and security

You sign in with a supported identity provider — such as Apple, Google, or Facebook where available — and are responsible for keeping access to your device and account secure. If you believe your device or account is compromised, you should treat it as you would any other private account and take steps to secure it.

Your content

The memories, words, photos, child profile details, and generated monthly letters you keep in the app remain yours. You give us the limited rights needed to host, process, sync, organize, generate, export, and show that content back to you inside the app. You are responsible for the content you choose to upload, store, edit, or share through the app, including whether it contains sensitive, private, or third-party information.

AI-assisted organization

Some functionalities of One Little Line are powered by AI. The app may use automated systems, models, or other software-assisted tools to organize, classify, summarize, suggest, sort, generate monthly letters, and otherwise support parts of the product experience. These tools may use the current month’s memories and recent prior entries for the same child context to improve tone and continuity. These features may change over time, may expand in scope, and may not always be accurate, complete, or suitable for every purpose.

Writing together (family)

You may invite another adult to help keep a child's memories, or join a family you are invited to. The person who created a child's profile is its owner and manages the family, including who can write and removing family members. Everyone in a child's family can see the memories, photos, and monthly letters connected to that child; you may edit or delete only the memories you wrote. Memories you write stay with the family if you leave or are removed, attributed to you. You are responsible for whom you invite and for the content you add to a shared child. If the adults in a child's family disagree (for example, parents who separate), the owner controls the profile and who it is shared with; we cannot mediate family disputes and will act only on the account-level controls and legal requirements available in the app. If you delete your account, you choose whether the memories you wrote remain with the family without your name or are deleted; ownership of a shared child transfers to a remaining member so the child's memories are not lost.

Plans, billing, and trial

One Little Line may offer free access, trials, paid subscriptions, or other paid features. Billing happens through the platform you use — Apple on iOS, Google Play on Android, or other services depending on the platform. Any subscription renews automatically at the price shown when you subscribed unless you cancel it at least 24 hours before the end of the current period. You can cancel at any time in your App Store account (Settings → your name → Subscriptions) or your Google Play account (Play Store → Payments & subscriptions → Subscriptions), or from Settings → Subscription → Manage subscription in the app. After you cancel, you keep access until the end of the period you have already paid for. The store may apply its own additional terms, billing rules, taxes, and payment rules.

Service providers

To provide a best-in-class service at a highly competitive cost, we work with trusted third-party providers that help us maintain a great experience for parents and caretakers. These currently include Supabase (authentication, database, storage, and server functions), Mistral AI (letter and tag generation), RevenueCat (subscription status), Apple and Google (sign-in, device services, and billing), Meta (Facebook sign-in, if you choose it), Expo (push notifications and app updates), Resend (lifecycle and transactional email delivery), and technical analytics and diagnostics tools such as PostHog and Sentry. Their roles and how they handle data are described in the Privacy Policy.

Memory limits and deletion

The app may apply writing, storage, export, or access limits on your memories depending on your plan or current product rules. If you delete a memory or delete your account, related data may still be retained by the service for up to 365 days for recovery, operational, security, fraud-prevention, billing, legal, or compliance purposes. If your paid access ends, your saved memories may be paused under the current product rules and removal from user access may be scheduled up to 60 days from the last successful payment, while retained data may still be kept internally for the longer retention periods described above.

Availability and changes

We reserve the right to adjust, modify, or discontinue the app, its functionalities, features, prices, and subscription packages as the product evolves; material changes to paid plans apply from your next billing period. We aim to keep the service available and reliable, but we cannot promise uninterrupted availability. Maintenance, outages, provider failures, and product changes can happen. We may add, remove, or change features over time.

Exports, backups, and ending use

You can export your memories and generated monthly letters from the app on both Apple and Google platforms, including PDF sharing where available. Keeping your own export is the best way to maintain an independent backup of important moments. If you manually share or export information from the app, you are responsible for that disclosure. We are not responsible for how that information is handled once you choose to share it outside the service. If you use sealing for monthly letters, that is an in-app preserved state and not permanent external storage. You can stop using the app at any time by signing out, canceling your subscription through the App Store or Google Play, deleting memories, or deleting your account from settings.

Reporting content

If you believe content stored in One Little Line infringes your copyright or other rights, or is otherwise illegal, email hello@onelittleline.com with a description of the content, where it appears, and why you believe it is unlawful. We review every notice, act on valid ones (which may include removing the content or suspending the account), and inform the person who added the content where appropriate. This address is also our single point of contact for users and authorities under the EU Digital Services Act.

Disclaimers and liability

To the extent permitted by law, the service is provided on an as-is and as-available basis. We do not promise that the app will always be error-free, uninterrupted, or suitable for every purpose. Nothing in these terms limits rights you may have under consumer law that cannot legally be excluded.

Communications

We send you service messages needed to run the app (for example, a monthly-letter-ready note, an account or deletion confirmation, or an export link). With your consent we may also send optional lifecycle and product update emails. You can turn optional categories on or off at any time in the app under Settings → Communications, or use the unsubscribe link in any such email; service and transactional messages may still be sent where necessary. Email is delivered through our email provider (see Service providers and the Privacy Policy).

Changes and contact

We may update these terms as the app evolves. When that happens, we will update this page and the in-app version. Questions about these terms? Contact us at hello@onelittleline.com.
