    This summary allows for layered reading. The following sections contain the complete information and prevail in case of doubt.

    1. Data controller and scope

    The data controller is Fernando Granado Castillo, Tax ID (NIF) 02668882P, domiciled at Calle Francisco Rivera, 28200 San Lorenzo del Escorial, Madrid, Spain. Privacy and contact email: ovinchi@ovinchi.com.

    This document applies to the Ovinchi mobile app, the ovinchi.com website, linked forms and associated digital services. Ovinchi has not appointed a Data Protection Officer. Queries are handled through the email above.

    2. Applicable principles

    Ovinchi processes data in accordance with the principles of lawfulness, fairness, transparency, purpose limitation, data minimization, accuracy, storage limitation, integrity and confidentiality.

    • •Only data appropriate for each feature will be requested.
    • •Optional data will not prevent account creation or access to features that do not need it.
    • •Personal content will not be used for personalized advertising nor sold to third parties.
    • •Consent-based features can be declined or disabled without affecting the rest of the service, unless the processing is essential to run that feature.

    3. Data we process and its source

    Most data comes directly from the user. Some identifiers and technical data are generated when using the app, logging in, receiving notifications or making a purchase.

    CategoryDataNature
    Account and identityName or alias, email, UID, sign-in method and Google or Apple identifiers.Account: required. Full name: optional if an alias is enough.
    BirthDate, time, place, time zone and coordinates of the place of birth.Required only for charts or calculations that need them.
    ProfileSelected sex, marital status, language, place of residence and preferences.Optional. Omitting it may reduce personalization.
    Personal contentQueries, follow-up questions, dreams, journal, goals, notes and emotional state.Optional and voluntarily provided.
    ImagesPhotograph of the palm and handwriting or signature sample.Optional and limited to the requested feature.
    AudioVoluntary recordings, transcription and meditation text sent for speech synthesis.Optional. Text input can always be used when the feature allows it.
    ResultsCharts, profiles, interpretations, meditations, audio and generated content.Required to deliver the requested service.
    PurchasesProduct, plan, credits, status, transaction and store identifiers.Required to manage purchases. Ovinchi does not receive full card data.
    Usage and deviceIP, device, version, language, usage events, installation identifier, push token and diagnostics.Security, operation, analytics and notifications.
    Support and rightsMessages, requests, identity verifications and exports.Required to handle the request.

    4. Mandatory data, optional data and accuracy

    The date, time and place of birth may be needed to run a BaZi, Human Design or astrology chart. They do not need to be requested before the user chooses a feature that needs them. Sex and marital status are optional and, when provided, are used to adapt certain interpretations. They will not prevent registration or the use of other features.

    The user must ensure that data is correct and keep it up to date. When the exact birth time is unknown, Ovinchi may allow an estimate, explaining that the result may be less accurate.

    5. Minors

    Minimum age: 14 years old

    Ovinchi does not allow users under 14 to create an account. Users aged 14 to 17 must have authorization and supervision from a parent or legal representative. Purchases and subscriptions made by minors require the authorization required under applicable law and Apple or Google rules.

    If Ovinchi detects an account belonging to a user under 14, it may suspend it and request the intervention of their legal representative, who may request access or deletion by writing to ovinchi@ovinchi.com. Ovinchi does not deliberately request information from minors that is not necessary for the service.

    6. Purposes and legal bases

    7. Especially sensitive information

    Journals, dreams, queries, goals or emotional states may incidentally reveal information about health, beliefs, sexuality, origin or other specially protected categories. Ovinchi does not require entering that information. When it is necessary for a chosen feature, explicit consent will be requested and the consequences of not granting it will be explained.

    • •Do not include sensitive data of third parties without authorization.
    • •Do not use Ovinchi to store clinical records, legal documentation or other people's secrets.
    • •You may delete content from the available features or request its erasure.

    8. Artificial intelligence and profiling

    Ovinchi uses artificial intelligence systems to combine calculations previously performed by its engines, interpret text and images, answer questions and generate meditations or profiles. Depending on availability and feature, OpenAI, Anthropic and Google Vertex AI/Gemini may be involved. Only the context reasonably necessary to produce the requested result will be sent.

    • •Before the first transfer of personal data to an AI provider, Ovinchi will inform of the data categories involved and request explicit permission.
    • •Providers act under their contracts and terms for enterprise or API services. Ovinchi does not voluntarily authorize training of general models with the content, unless new information and consent are provided when required.
    • •Results are automated, interpretative and may contain errors, omissions or inaccurate information.
    • •Ovinchi does not use these profiles to make legal decisions or decisions producing significantly similar effects on the user.
    • •Withdrawing permission will prevent new transfers to AI and may disable the features that depend on that processing, without affecting other independent features.

    9. Palm and handwriting images

    Photographs of the palm and handwriting samples are used to generate the requested interpretations. They are not used to authenticate the user or to uniquely identify them. Even so, they are personal data of particular practical sensitivity and may be subject to automated analysis of traits or patterns.

    • •Providing these images is optional.
    • •A signature used in banking, administrative or contractual documents should not be sent if it can be avoided; a sample created specifically for Ovinchi is recommended.
    • •Images will only be kept for the period stated in the retention section and will be deleted along with the account or upon user request.

    10. Voice, transcription and ElevenLabs

    When the user records audio to dictate a dream, an entry or a query, the audio may be sent to ElevenLabs to convert it into text. To generate certain meditations, text may be sent to the same provider to obtain audio. Ovinchi uses a Standard plan, so it cannot promise zero retention within ElevenLabs' systems.

    • •Ovinchi processes dictation audio transiently and does not intend to keep the original file after receiving the transcription.
    • •ElevenLabs may retain requests, responses or logs in accordance with its policy, account configuration and security or moderation needs.
    • •Depending on the provider's configuration, certain data may be used to improve its services. Ovinchi will review and limit that option when available.
    • •The user can avoid this processing by typing content instead of using the microphone.

    Provider information: ElevenLabs Privacy Policy.

    11. Third-party data

    Compatibility features may allow entering another person's data, such as name or alias and birth data. The user represents that they are authorized to provide it and will use it only for a personal and legitimate purpose. Ovinchi does not create an account for that person and should not receive unnecessary sensitive information about them.

    When applicable under Article 14 of the GDPR, the user must provide that person with basic information about the processing or collaborate with Ovinchi to do so. Ovinchi may remove content that infringes third-party rights.

    12. Recipients and providers

    RecipientPurposeData
    Google Cloud / FirebaseAuthentication, database, storage, infrastructure, notifications, security, analytics and error reporting.Account, content, files, usage, device and diagnostics.
    OpenAIGeneration or analysis using AI models via API services.Context, queries, precomputed profiles, necessary text and images.
    AnthropicGeneration, analysis, unification and AI safety controls.Context, queries, text, prior results and necessary data.
    Google Vertex AI / GeminiGenerative models and text or image processing.Context, queries, profiles, necessary text and images.
    ElevenLabsVoice transcription and audio synthesis.Audio, transcription, language and meditation text.
    Google GmailSending the requested data export by email.User email and export file.
    Apple and GoogleSign-in, distribution, purchases, subscriptions and payment management.Social account, store, product and transaction identifiers.
    Authorities and advisorsLegal compliance, defense of claims and fraud prevention.Only the data required or necessary in each case.

    Ovinchi contractually requires processors to apply guarantees of confidentiality, security, assistance with rights requests, erasure and equivalent protection. Apple, Google or other providers may act as independent controllers for their own services, under their own policies.

    13. International transfers

    Some providers or subprocessors may process data outside the European Economic Area, particularly in the United States. Ovinchi will apply the valid mechanism stated in each provider's contract: an adequacy decision, the EU-U.S. Data Privacy Framework where applicable, Standard Contractual Clauses approved by the European Commission, or other safeguards permitted under the GDPR.

    The user may request additional information about the safeguards by writing to ovinchi@ovinchi.com. Merely accepting the terms does not replace the contractual guarantees required for an international transfer.

    14. Retention periods

    ProcessingPeriod or criterion
    Account and profileWhile the account is active. After requesting deletion, the account is deactivated and enters an ordinary 30-day grace period before purging.
    Queries, journals, dreams, goals and resultsUntil deleted by the user where that option exists, or until the account is finally deleted.
    Palm or handwriting imagesWhile necessary for the feature and, at most, until the associated content or account is deleted.
    Dictation audioOvinchi keeps it only during transcription. ElevenLabs may apply the retention of its Standard plan and its security logs.
    Meditations and generated audioWhile available to the user or until the associated content or account is deleted.
    AI operational inputs and outputsWhile necessary to provide and display the service, or until the account is deleted, except for limited provider security logs.
    AnalyticsUp to 14 months for event data, with periodic review and aggregation where possible.
    Errors and securityUp to 90 days, unless an incident requires keeping evidence for the period necessary to investigate it or defend claims.
    NotificationsUntil notifications are disabled, the user logs out permanently, or the account is deleted.
    Purchases and billingPersonal identifiers are anonymized upon account deletion where possible. Legally required records may be kept for up to 6 years.
    Proof of consents, rights and claimsUp to 5 years from withdrawal, closure or resolution, to evidence compliance and address possible liabilities.
    Specialist requests12 months if the process does not continue; if a relationship is established, for its duration plus subsequent legal periods.
    BackupsDeletion propagates during the ordinary rotation cycle. Data remains blocked and is not reintroduced except for disaster recovery.

    When there is a legal obligation, litigation, fraud or incident, certain data may be blocked for the period strictly necessary. Once that period ends, it will be irreversibly deleted or anonymized.

    15. Consent and withdrawal

    When processing depends on consent, Ovinchi will request an affirmative, informed action separated by purpose. Silence, inactivity or a pre-checked box will not be considered consent.

    • •Accepting the Terms of Use is independent from confirming that this policy has been read.
    • •Permission for AI, especially sensitive data, voice, analytics and marketing communications will be managed separately where applicable.
    • •The user may withdraw consent through the available controls or by writing to ovinchi@ovinchi.com.
    • •Withdrawal does not affect the lawfulness of prior processing, but may prevent using the feature that needs that data.

    16. User rights

    The user may exercise the following rights free of charge:

    • •Access: to know whether their data is being processed and obtain a copy.
    • •Rectification: to correct inaccurate or incomplete data.
    • •Erasure: to request deletion where applicable.
    • •Objection: to object to processing based on legitimate interest, including certain analytics.
    • •Restriction: to request that data be blocked in the legally established cases.
    • •Portability: to receive the data provided in a structured format where applicable.
    • •Withdrawal of consent and the right not to be subject to automated decisions with legal or similarly significant effects.

    The request can be sent to ovinchi@ovinchi.com stating the right exercised. Ovinchi may request information to verify identity without collecting excessive data. It will generally respond within one month, extendable in the cases provided for by the GDPR.

    You may also lodge a complaint with the Spanish Data Protection Agency (AEPD), C/ Jorge Juan 6, 28001 Madrid.

    17. Data export and account deletion

    The user may request an export of their data. Ovinchi generates a file and sends it to the associated email via Google Gmail. The file may include especially private information, so the user must protect their mailbox and delete copies no longer needed. Google will process the message under its own terms and policy.

    Account deletion is requested from within the app. The account is deactivated immediately and, after the ordinary 30-day grace period, account, database, storage and authentication data are purged, except for anonymized, blocked or legally required information.

    Subscription and account are separate matters

    Deleting an Ovinchi account does not guarantee cancellation of a subscription billed by Apple or Google. The user must cancel the renewal in the corresponding store. Likewise, canceling the subscription does not delete the account or its data.

    18. Security and breaches

    Ovinchi applies technical and organizational measures proportionate to the risk, such as access control, environment separation, encryption in transit, credential protection, security logging and Firebase access rules. No system is infallible, and the user must also protect their device and credentials.

    If a security breach occurs that poses a risk to individuals, Ovinchi will assess the incident, document it and notify the authority and affected individuals when required by law.

    19. Changes to this policy

    Ovinchi may update this policy due to legal, technical or functional changes. Material modifications will be communicated visibly. If a new purpose requires consent, it will be requested before starting the processing. The version, date and effective date will appear at the beginning of the document.
