Privacy Policy

Information we collect

• Account: you sign in with Apple or Google. From them we receive an account identifier, your email address (with Apple this may be a private relay address if you choose to hide your email) and, if you share it, your name. We also keep your display name, language, time zone and country, and the date you gave parental consent. We never see your Apple or Google password.
• Child profiles you create: name and nickname, birth date or age, gender, language, avatar and color, and anything you choose to add, such as interests, favorites, routines, challenges and notes for the heroes.
• Calls: during a call your child's voice is streamed to our servers and turned into text. We keep the text of what was said (the transcript), a short summary, the mission and how it went, the call's length, and the rating you give a call. The audio itself is never recorded or stored.
• Hero memories: after a call, short notes the hero should remember next time (for example "loves dinosaurs"). You can view, add, pin or delete them, or switch memory off for a child.
• Custom heroes: the name, role, description, catchphrase and picture you give a hero in Hero Studio. Custom heroes are private to your family.
• Purchases: which product was bought, the store transaction ID, the subscription period and its status, as reported by Apple or Google. We never receive your card or payment details.
• Technical data: the app version, device platform and the tokens that keep you signed in, plus server logs (such as IP address and error reports) kept for security and troubleshooting.

What we never collect

We do not collect your child's location, contacts, photos of your child or advertising identifiers. The app contains no advertising, no third-party analytics or tracking SDKs, and we do not build advertising profiles or sell or rent anyone's data.

How we use information

• To run hero calls: understand what your child says, let the hero answer in your language, and call your child by name.
• To keep children safe: every sentence a hero says is checked before it is spoken, and calls where a child mentions harm, danger or distress are flagged so you can see them. Flagged moments may be reviewed by our safety team.
• To show you call reports, summaries and transcripts, run schedules, and enforce the calling hours and daily limits you set.
• To deliver purchases, keep track of minutes and subscriptions, and prevent fraud.
• To answer support requests and to keep the service secure and working.

Service providers who process data for us

We use a small number of providers who process data only on our behalf, to provide the service:

• Groq: speech-to-text for your child's voice, and safety checks. Audio is sent to Groq while the call happens.
• The AI that writes the hero's replies and the call summaries: depending on the plan and our settings, Anthropic (Claude), Google (Gemini), Groq or DeepSeek. They receive the conversation text and the details the hero needs from the child's profile (first name or nickname, age, interests and the memories you can see in the app), never your child's voice or your contact details.
• OpenAI and ElevenLabs: turning the hero's sentences into speech. They receive the text the hero says, not your child's voice.
• DigitalOcean: our servers and database, located in Singapore.
• Cloudflare: hosting of this website.
• Apple and Google: signing in to your account, in-app purchases and subscriptions, under their own privacy policies.

Because these providers operate in several countries (including Singapore, the United States and, when DeepSeek is used, China), your information may be processed outside the country where you live. We only share what each provider needs for its task, and we ask for your permission before your child's first call.

How long we keep information

• Voice audio: never stored; it is processed in memory for a few seconds.
• Transcripts: deleted automatically after 30 days, or straight away when you delete it from the call.
• Safety records: when a call is flagged, or when you report what a hero said, our safety team keeps a record of it. The words it quotes are removed after 30 days, or straight away when you delete that call's transcript; the rest of the record is deleted with your account.
• Hero memories, child profiles and custom heroes: until you delete them or your account.
• Account: until you delete it. Deleting your account in the app removes your profile, your children's profiles, calls, transcripts, memories and custom heroes, and revokes HeroCall's access to your Sign in with Apple account. Records of purchases are kept, detached from your account, where tax and accounting law requires.
• Server logs: kept for a limited time for security, then deleted.

Children's privacy

HeroCall is designed for families with children aged about 3 to 12. Only a parent or guardian aged 18 or over can create an account, and the app asks for parental consent before any call. Children never create accounts, never see purchase screens and cannot leave Kid Mode without the parent.

As a parent you can review everything we hold about your child (profile, call summaries, transcripts and memories), delete any part of it, switch off memory or calls started by your child, or delete your child's profile entirely, all from the app. You can also ask us to do this by email. We do not ask children for personal details, and heroes are instructed never to ask for or repeat information such as addresses, schools, phone numbers or passwords.

Your rights and choices

Depending on where you live, you may have the right to access, correct, delete or export your information, to object to or restrict how we use it, and to withdraw consent. Most of this can be done directly in the app (Settings and each child's page). For anything else, email company@isemi.io; we answer within 30 days. You may also complain to your local data protection authority.

Security

Data is encrypted in transit, sign-in tokens are stored encrypted, and access to production data is limited to the people who need it to run and protect the service. No system is perfectly secure, but we work to protect your information and will notify you and the authorities of a breach as the law requires.

Permissions

The app asks for the microphone, so your child can talk with heroes, and for notifications, so scheduled hero calls can ring. If you add a picture to a custom hero, it asks to open your photo library for the picture you choose. It never asks for location or contacts.

Changes to this policy

If we change how the app handles data, we will update this page and the date at the top before the change takes effect, and tell you in the app when the change is significant.
