Privacy Policy

Last updated: 2 November 2026

This Privacy Policy applies to Hermes Chat, also listed as “World History AI Tutor Chat” (App Store ID 6447547239), and its AI and support services. The operator and data controller is Remione LTD, 75 Leontiou Machaira, Centre, Office 102, Limassol 3025, Cyprus. Alexey Strokin is the App Store publisher acting on behalf of Remione LTD. A provider may separately act as controller for its own services, such as Apple's transactions.

For privacy questions, withdrawal or deletion requests, email info@remione.ltd. App support is available at support.team@hermeschat.app. Please identify the app as Hermes Chat or World History AI Tutor Chat.

Hermes offers educational conversations with AI simulations of historical figures, character discovery, learning prompts, interests and local chat history. You do not create a separate registered Hermes account. Installation identifiers, chat content and purchase profiles can nevertheless be personal data.

Before sending a message: the current conversation history, selected character/topic instructions and an installation identifier are sent through our backend to OpenAI. Chat history can also be copied to your Apple iCloud storage when available. Deleting local history does not reliably erase all cloud copies or provider records. Reading this policy or buying a subscription does not replace separate consent where required.

1. Information processed and its purposes

2. How AI conversations work

When you send a message, a suggested question or a learning action such as “Explain simpler”, “Make a timeline” or “Quiz me”, Hermes sends the conversation's messages and roles, character instructions, selected topic constraints, generation settings and your installation identifier to our HTTPS backend. The backend forwards the request to OpenAI to generate an answer and returns it to your device. The identifier is included in the AI request as a user reference. Hermes' chat feature processes text conversations.

The current backend handles requests and responses rather than maintaining a personal server-side chat-history account. Its application request logs record operational fields such as request IDs, route, status and timing rather than conversation bodies. This does not mean that conversations never leave the device or that all services have zero retention. Local app diagnostics, voluntarily sent reports and provider-side processing have separate scopes and retention.

OpenAI states that API data is not used to train its models by default unless the API customer opts in. Its standard abuse-monitoring logs can include inputs and outputs and are generally retained for up to 30 days, with legal and safety exceptions. Additional feature-specific processing can apply. See OpenAI API data controls and OpenAI's Privacy Policy. We do not claim a zero-retention arrangement for Hermes.

Do not send passwords, payment-card details, private documents or sensitive information that is unnecessary for a historical conversation. Only include another person's information if you have the right and any necessary permission to do so. We do not publish your private conversations in a public feed or grant ourselves a right to advertise with them through this policy.

The current version does not provide a separate in-app control for consenting to or withdrawing from OpenAI sharing. Accepting the Terms, starting a subscription or reading this notice is not a substitute for explicit permission where required. To avoid new AI transmissions, do not send messages, suggested questions or learning actions. Previous requests and records are addressed through the rights and deletion process below.

3. Local history and iCloud

Chats, saved messages, character information and interest preferences are stored in a local database. Where the app's iCloud container is available, Hermes can automatically copy that database to your Apple iCloud storage when the app becomes inactive and restore an available copy when it becomes active. This operates through Apple, independently of our AI backend, and is subject to your Apple Account and iCloud settings.

The current sync implementation does not propagate an empty local history as deletion of the existing iCloud copy. As a result, clearing all chats locally or reinstalling can leave an older cloud database available to restore. Resetting one conversation also does not constitute a verified erasure of every underlying database record. Do not treat these actions as a request to erase data from all services.

Use the available iCloud controls in your Apple device settings to manage or remove Hermes iCloud data, and manage other device backups separately. Disabling future sync does not by itself prove that an existing cloud copy has been deleted. Contact support if you need help locating these controls. We cannot sign in to or delete data from your personal Apple Account for you.

4. Service providers and other recipients

The services below receive information relevant to their roles; the precise collection depends on the feature, version, configuration and applicable permissions:

We require providers processing user data on our behalf to limit use to agreed purposes, protect confidentiality and security, and provide protection at least equivalent to this policy and applicable Apple requirements. Their notices do not remove our responsibility for the app's processing and choices.

We may disclose necessary information to comply with law, protect rights, investigate abuse, obtain professional advice or complete a business transfer with applicable safeguards. When you copy or share a reply through another service, that recipient processes the copy under its own terms. We do not sell personal data for money; advertising-measurement disclosures may still fall within legal definitions of sale, sharing or targeted advertising, and the relevant opt-out and consent rights apply.

5. Purposes, legal bases and choices

Where GDPR or similar law applies, necessary service delivery, purchases and requested support rely on performance of our contract or steps you request. Proportionate security, abuse prevention and reliability work may rely on legitimate interests, subject to your rights. Required records and lawful disclosures rely on legal obligations. Where consent is required for analytics, tracking, device access or sharing personal data with AI, it must be obtained for that purpose and can be withdrawn. A contract or legitimate interest does not override a consent requirement.

Providing chat content and interests is your choice. The AI feature needs the content you send to produce a contextual response; information for a support request must be sufficient to address it. We do not use AI answers to make solely automated decisions about you that produce legal or similarly significant effects.

Declining optional tracking or unrelated permissions must not remove purchased features that do not require those permissions. Withdrawing consent does not affect earlier lawful processing or cancel a subscription.

6. Retention and deletion requests

To request deletion of data we control, email info@remione.ltd with “Hermes data deletion” and enough information to locate it, such as the email used for support, approximate request date or a relevant purchase reference. We may ask for proportionate verification or help locate your installation identifier. Do not send your Apple password, payment-card details or unnecessary copies of private conversations. We will address identifiable records and our processors where applicable, explaining lawful exceptions or identification limits. Protected backups may remain until expiry; irreversibly anonymized statistics may be retained.

There is no separate registered Hermes account to close. Deletion of app data does not cancel billing by Apple, and we cannot erase your Apple Account or independent records that Apple must retain.

7. Your rights

Depending on your location, you may request access, a copy, correction, deletion, restriction or portability of personal data; object to processing, including marketing; withdraw consent; and exercise applicable sale/sharing or targeted-advertising opt-outs. Contact info@remione.ltd. We do not unlawfully discriminate for exercising these rights. Under GDPR, we respond without undue delay and normally within one month, with notice and reasons if a lawful extension is needed. Other applicable statutory deadlines and appeal rights are respected.

You may complain to your local authority or the Cyprus Commissioner for Personal Data Protection without contacting us first.

8. International processing and security

Remione LTD is based in Cyprus. Cloud, AI, purchase and analytics providers may process data in the United States and other countries outside your country of residence. Transfers covered by EEA, UK or Swiss rules require an applicable adequacy decision or appropriate safeguards, such as standard contractual clauses and necessary supplementary measures. Contact us for information about applicable safeguards and how to obtain a copy.

The chat endpoint uses HTTPS. Access controls and other safeguards must be appropriate to the information and risks. Conversations are readable by the backend and AI provider during processing; they are not end-to-end encrypted against those services. No system is entirely secure. Protect your device, Apple Account and diagnostic attachments.

9. Children

The service is not directed to children under 13. A higher minimum age or parental authorization may be required by local law. Hermes does not ask for a date of birth, and an App Store content rating is not consent to analytics, tracking, purchases or AI sharing. If you believe a child has supplied information without required authorization, contact us so we can investigate and take appropriate deletion or restriction steps.

10. These pages and changes

Opening a legal page sends ordinary connection information, including your IP address, to our web host. The Hermes Terms and Privacy pages can be read without an account or JavaScript and do not load the website's analytics script. Other Remione pages and external sites may have different analytics or cookie practices.

We may update this policy when practices or legal requirements change. The date above identifies this revision. Material changes require appropriate notice and fresh consent where applicable; posting a new notice or continued use does not itself authorize processing that requires separate permission. See the Hermes Terms & Conditions for service and purchase conditions.
