Please read these Terms carefully.
Terms of Use, Sale & End-User License Agreement
Last updated: September 9, 2026
These Terms of Use, Sale & End-User License Agreement (“Terms”) form a binding agreement between you and Callsy SAS (“Callsy,” “MystiCall,” “we,” “us,” or “our”) governing your access to and use of the MystiCall mobile application, website, AI-powered features, voice experiences, readings, content, purchases, subscriptions and related services (collectively, the “Service”).
By creating an account, expressly accepting these Terms, using paid features, or otherwise using the Service after being given legally sufficient notice of these Terms, you agree to be bound by them.
If you do not agree, do not use MystiCall.
1. Company information
MystiCall is operated by:
Callsy SAS SIREN / RCS: 989 559 596 R.C.S. Paris SIRET: 989 559 596 00022 Share capital: €100 Registered office: 58 rue de Monceau, 75008 Paris, France Email: hello@mysticall.ai
2. Age requirement — 18+ only
MystiCall is intended only for adults aged 18 or over.
By using the Service, you represent and warrant that you are at least 18 years old and legally capable of entering into these Terms.
We may suspend or terminate an account if we reasonably believe the user is under 18 or has provided false age information.
MystiCall is not directed to children or teenagers.
3. What MystiCall is — entertainment and reflection only
MystiCall is an AI-powered entertainment, reflection and personal-exploration experience.
Features may include, for example:
- daily signs or omens;
- tarot and symbolic readings;
- astrology- or numerology-inspired content;
- relationship or connection reflections;
- saved readings and personal insights;
- AI-generated text or audio;
- an AI voice guide;
- personalization or memory features based on information you choose to provide.
MystiCall does not possess supernatural powers and does not guarantee the prediction, detection or determination of future events, another person’s thoughts, intentions, emotions, fidelity, actions, location, health, legal situation, financial condition, or any other factual circumstance.
Any tarot, astrology, numerology, “energy,” intuitive, symbolic, spiritual, psychic-style or similar material is presented as fictionalized, symbolic, entertainment-oriented or reflective content, not as verified fact.
You should treat outputs as prompts for reflection rather than facts on which to make consequential decisions.
4. You are interacting with artificial intelligence
MystiCall uses artificial intelligence. Unless expressly stated otherwise, you are not communicating with a human psychic, counselor, therapist, coach, doctor, lawyer, financial adviser or emergency responder.
AI-generated outputs may be:
- incorrect;
- incomplete;
- inconsistent;
- unexpected;
- unsuitable for your circumstances;
- influenced by the information you provide.
You are responsible for independently evaluating any output before relying on it.
5. No professional advice; no emergency use
MystiCall does not provide medical, psychiatric, psychological, therapeutic, legal, tax, financial, investment, employment, immigration, safety or other regulated professional advice.
Do not use MystiCall:
- to diagnose or treat a health or mental-health condition;
- to decide whether to seek medical or emergency care;
- to make investment, legal or financial decisions;
- to determine whether another person poses a danger;
- as a substitute for qualified professional advice;
- as an emergency or crisis service.
If you believe you or another person may be in immediate danger, contact the appropriate local emergency service or qualified professional.
6. Personal responsibility and no reliance
You remain solely responsible for your choices, communications, relationships, purchases, travel, health decisions, legal decisions, financial decisions and other actions.
You agree not to treat MystiCall output as a guarantee, instruction, diagnosis, professional opinion or factual statement about another person.
To the fullest extent permitted by applicable law, you assume the risks associated with acting on AI-generated, symbolic or entertainment-oriented content.
7. Accounts
Certain features require an account.
You agree to:
- provide accurate information;
- keep access credentials and devices secure;
- promptly notify us of suspected unauthorized use;
- not impersonate another person;
- not create accounts using fraudulent information;
- not sell, transfer or share an account in a way that compromises security.
We may implement authentication, anti-fraud or account-recovery controls.
8. Personalization, memory and conversation continuity
MystiCall may use information you choose to provide to personalize the Service.
Where memory features are enabled, we may retain or generate summaries, preferences, themes, selected facts or other limited contextual information so that future interactions can continue from relevant prior context.
Memory is designed for continuity; it does not mean that MystiCall has human memory, consciousness, awareness or a personal relationship with you.
You may request deletion as described in the Privacy Policy, subject to legally required retention.
9. Sensitive information and information about others
Do not provide:
- passwords;
- full payment-card details;
- government identification numbers unless explicitly requested through a secure process;
- confidential third-party information you have no right to disclose;
- highly sensitive information that is not necessary to receive the Service.
If you discuss another person, you are responsible for ensuring that you have a lawful basis to provide any personal information you share about them.
MystiCall should not be used to stalk, monitor, identify, locate, harass or infer protected or highly sensitive attributes about another person.
10. Purchases, digital content and subscriptions
MystiCall may offer:
- free features;
- one-time digital purchases;
- consumable digital items;
- paid readings or experiences;
- free trials or introductory offers;
- auto-renewing subscriptions.
The exact product, price, currency, billing period, trial terms, renewal terms and included features displayed at the point of purchase control for that transaction.
App-store purchases
When payment is processed through the Apple App Store or Google Play, the relevant store processes payment and may also govern billing, taxes, subscription management, cancellation and store-level refund handling.
You must comply with the applicable app-store terms.
Auto-renewing subscriptions
If you purchase an auto-renewing subscription:
- the purchase screen will identify that the subscription renews automatically;
- the price and billing period will be displayed before purchase;
- you will be charged through the applicable store unless you cancel in accordance with that store’s process;
- cancellation stops future renewal but generally does not retroactively cancel an already-completed billing period unless applicable law or store policy requires otherwise;
- if a free trial converts to a paid subscription, the conversion terms will be displayed before enrollment.
We will not intentionally use hidden terms, pre-checked consent, misleading countdowns or unnecessary cancellation barriers.
Price changes
Price changes will be handled in accordance with applicable law and the rules of the relevant app store.
11. Refunds
Refund rights vary by location, purchase type and payment platform.
For purchases processed by Apple or Google, requests may be handled under the relevant store’s refund process and mandatory law.
Nothing in these Terms limits any non-waivable refund, withdrawal, conformity or consumer right that applies to you.
Except where required by applicable law or store policy, consumed or delivered digital content may be non-refundable.
Where applicable law requires prior express consent and acknowledgement before the immediate supply of digital content affects a statutory withdrawal right, any loss of that right applies only after those requirements have been validly satisfied through the applicable checkout flow. Nothing in these Terms removes non-waivable statutory rights or rights provided by Apple or Google.
12. Taxes
Prices may include or exclude taxes depending on the platform, country and applicable rules.
App stores may calculate, collect and remit taxes as required.
13. Acceptable use
You may not use MystiCall to:
- violate any law;
- defraud or deceive another person;
- harass, threaten, stalk, exploit or abuse anyone;

- impersonate another person;
- exploit a vulnerable person;
- interfere with or disrupt the Service;
- bypass security or access controls;
- reverse engineer the Service except where such restriction is prohibited by law;
- scrape, crawl, copy or extract the Service through automated means without authorization;
- use the Service to create competing datasets, models or services in violation of our rights;
- upload malicious code;
- submit content you have no right to provide;
- use MystiCall output as a fraudulent credential, diagnosis, professional certification or factual verification.
We may investigate suspected abuse and restrict access where reasonably necessary.
14. Prohibited high-risk reliance
You must not use MystiCall as the sole or primary basis for decisions involving:
- medical treatment;
- self-harm or suicide;

- legal rights or deadlines;
- investments or financial transactions;
- employment;

- credit;
- other decisions that can materially affect a person’s rights, safety or livelihood.
15. User content

You grant Callsy a limited, worldwide, non-exclusive license to host, process, reproduce, transmit and technically transform your content only as reasonably necessary to:
- provide the Service;

- comply with law;
- exercise or defend legal rights.
This license does not transfer ownership of your content to Callsy.
Our use of personal data is governed by the Privacy Policy.
16. Feedback
If you voluntarily submit product feedback, suggestions or ideas, you grant Callsy the right to use that feedback without restriction or compensation, provided we do not publicly identify you without permission.
17. MystiCall intellectual property
The Service and its original elements — including software, branding, product design, text, visuals, sounds, characters, prompts, workflows, curated readings and editorial content — are owned by or licensed to Callsy and protected by intellectual-property laws.
Subject to these Terms, Callsy grants you a limited, personal, revocable, non-exclusive, non-transferable license to use MystiCall for your personal, non-commercial use.
No other rights are granted.
18. Third-party services
MystiCall may rely on third-party technology providers and app stores.
Third-party services may be subject to their own terms and privacy practices.
We are not responsible for third-party services to the extent prohibited from being attributed to us by applicable law, but nothing in these Terms limits liability that cannot lawfully be excluded.
19. Service changes and availability
We may modify, improve, suspend or discontinue features where reasonably necessary for product, legal, security, technical or business reasons.
We do not guarantee uninterrupted, error-free or permanent availability.
Where applicable law requires advance notice of a material change to a paid service, we will provide it.
20. Beta and experimental features
Features identified as beta, preview, experimental or similar may be incomplete, change without notice and contain more errors than generally released features.
Use them at your own risk to the fullest extent permitted by law.
21. Suspension and termination
We may suspend or terminate access where reasonably necessary because of:
- fraud;
- abuse;
- security risk;
- legal requirements;
- material breach of these Terms;
- misuse that creates risk for users, Callsy or third parties.
Where appropriate and legally required, we may provide notice and an opportunity to remedy.
You may stop using MystiCall at any time.
Account deletion is addressed in the Privacy Policy and at /delete-account.
22. Disclaimers of warranties
FOR USERS OUTSIDE JURISDICTIONS WHERE THESE DISCLAIMERS ARE PROHIBITED:
TO THE FULLEST EXTENT PERMITTED BY LAW, THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE.”
CALLSY DISCLAIMS ALL WARRANTIES, REPRESENTATIONS AND CONDITIONS NOT EXPRESSLY STATED IN THESE TERMS, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, QUIET ENJOYMENT, NON-INFRINGEMENT, ACCURACY AND RELIABILITY.
WE DO NOT WARRANT THAT:
- MYSTICALL WILL BE UNINTERRUPTED OR ERROR-FREE;
- AI OUTPUTS WILL BE ACCURATE;
- A READING OR GUIDANCE WILL PREDICT AN EVENT;
- ANOTHER PERSON WILL ACT IN A PARTICULAR WAY;
- THE SERVICE WILL ACHIEVE A PARTICULAR EMOTIONAL, RELATIONSHIP, FINANCIAL OR PERSONAL RESULT.
Mandatory consumer warranties remain unaffected.
23. Limitation of liability
TO THE FULLEST EXTENT PERMITTED BY LAW, CALLSY AND ITS DIRECTORS, OFFICERS, EMPLOYEES, CONTRACTORS AND AFFILIATES WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, CONSEQUENTIAL OR PUNITIVE DAMAGES, OR FOR LOSS OF PROFITS, REVENUE, DATA, GOODWILL OR BUSINESS OPPORTUNITY ARISING FROM OR RELATING TO THE SERVICE.
TO THE FULLEST EXTENT PERMITTED BY LAW, CALLSY’S TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS WILL NOT EXCEED THE GREATER OF:
1. THE AMOUNT YOU PAID TO CALLSY OR THROUGH THE APPLICABLE APP STORE FOR MYSTICALL DURING THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM; OR 2. USD $100.
This limitation does not apply where prohibited by law and does not exclude liability for fraud, willful misconduct, gross negligence where non-excludable, death or personal injury caused by negligence where non-excludable, or mandatory consumer rights.
Some jurisdictions do not allow certain exclusions or limitations. In those jurisdictions, these provisions apply only to the maximum extent permitted.
24. Indemnification for misuse
To the extent permitted by applicable law, you agree to defend, indemnify and hold harmless Callsy from third-party claims, losses and reasonable costs arising from your:
- unlawful use of the Service;
- material breach of these Terms;
- infringement of another person’s rights;
- submission of content you had no right to provide;
- fraudulent or abusive conduct.
This section does not require consumers to indemnify Callsy for Callsy’s own negligence, unlawful conduct or breach of mandatory obligations.
25. No fiduciary or professional relationship
Your use of MystiCall does not create a fiduciary, therapist-patient, doctor-patient, lawyer-client, adviser-client, employment, agency, partnership or joint-venture relationship with Callsy.
26. Force majeure
To the extent permitted by law, Callsy is not responsible for delay or failure caused by events reasonably beyond its control, including network failures, infrastructure outages, cyberattacks, acts of government, natural disasters, war, civil unrest, labor disruptions or failures of critical third-party infrastructure.
27. Export and sanctions compliance
You may not use the Service in violation of applicable export-control, sanctions or trade laws.
You represent that you are not prohibited from receiving the Service under applicable sanctions laws.
28. Changes to these Terms
We may update these Terms.
For material changes affecting an ongoing paid relationship, we will provide notice and, where required, obtain renewed acceptance.
The version and effective date will be displayed.
Your continued use after a legally valid change takes effect constitutes acceptance only where permitted by applicable law.
29. Governing law and mandatory consumer rights
Except as stated in the U.S. dispute-resolution section below, these Terms are governed by French law.
If you are a consumer, this choice does not deprive you of mandatory protections available under the law of your habitual residence where such protections cannot lawfully be waived.
For users who are not consumers, the courts of Paris, France have exclusive jurisdiction unless applicable law requires otherwise.
30. Informal dispute resolution
Before filing a formal claim, you and Callsy agree, where lawful, to attempt in good faith to resolve the dispute informally.
Send a written notice to hello@mysticall.ai identifying:
- your name and account email;
- the nature of the dispute;
- the relief requested;
- enough information for us to investigate.
The parties will attempt to resolve the matter for at least 30 days before formal proceedings, unless immediate action is necessary to preserve rights or applicable law prohibits this requirement.
31. U.S. users — consumer rights and disputes
If you are a consumer in the United States, you retain all non-waivable rights available under applicable federal and state law. Nothing in these Terms requires you to waive a right or remedy that cannot lawfully be waived.
Before starting formal proceedings, please contact hello@mysticall.ai so that you and Callsy can try in good faith to resolve the issue, unless applicable law allows or requires immediate action.
32. French consumer mediation
If you are a consumer covered by French consumer-mediation rules, after first contacting Callsy in writing and if the response does not resolve the dispute, you may use the following consumer mediation service free of charge:
CM2C — 49 rue de Ponthieu, 75008 Paris, France — Telephone: +33 (0)1 89 47 00 14 — Website: https://www.cm2c.net/declarer-un-litige.php — Email: litiges@cm2c.net
This mediation information applies only where the consumer and dispute are eligible under the applicable rules.
33. Severability
If any provision is held invalid or unenforceable, it will be enforced to the maximum lawful extent or severed, and the remaining provisions will remain in effect, unless applicable law requires a different result.
34. No waiver
Failure to enforce a provision is not a waiver of our right to do so later.
35. Assignment
You may not assign these Terms without our prior written consent.
Callsy may assign these Terms as part of a merger, reorganization, financing, sale of assets or transfer of the Service, subject to applicable law.
36. Entire agreement
