Summary: your content remains yours; myrna receives only the technical license needed to operate. AI and integrations send data when invoked. Plans renew until cancelled, and mandatory consumer rights remain protected.
1. The agreement and your acceptance
These Terms of Use (“Terms”) form a contract between you and myrna, the operator of myrna (“myrna,” the “Service,” “we,” or “us”). They govern the website, application, APIs, collaboration features, storage, and related services.
By creating an account, clicking to accept, or using the Service, you confirm that you have read and agree to these Terms, the Privacy Policy, and, where applicable, the Report and Takedown Policy. If you disagree, do not use the Service.
Offers, pricing pages, and specific terms shown at purchase supplement these Terms. If they conflict, the specific terms you accepted control their subject matter, without waiving mandatory legal rights.
2. Eligibility and organizational use
You must have legal capacity to contract. The Service is intended for adults. Users under 18 may use it only with authorization and supervision from a legal guardian; it is not directed to children under 13.
If you use the Service for a company, university, research group, or other organization, you represent that you can bind it to these Terms. In that case, “you” includes the organization, which is responsible for accounts, permissions, and content under its administration.
Team owners and administrators may invite or remove members, change roles and permissions, and access information needed to manage the shared environment. Organizations must notify members of internal rules and establish an appropriate legal basis for personal data entered into the Service.
3. Registration, credentials, and account security
You must provide accurate, current information; secure your credentials, devices, recovery keys, and API tokens; and not share an individual account. You are responsible for actions performed with your credentials until you report misuse, except where responsibility legally belongs to us.
Immediately contact suporte@myrna.app if you suspect unauthorized access. We may verify identity, reset sessions, or block credentials to protect you, other users, and the infrastructure.
Sign-in through an external provider such as Google is also subject to that provider’s terms and controls. Provider unavailability or revocation may affect that sign-in method.
4. The Service, plans, limits, and experimental features
myrna includes notes, tasks, calendar, journal, contacts, databases, forms, boards, and bibliographic references, together with sharing, storage, and optional features. Module, collaboration, AI, and storage availability depends on your plan, environment configuration, and development stage.
Quantity, file size, storage, request, and reasonable-use limits are shown in the app or pricing page and may be enforced for security and sustainability. Excess files may be rejected; we will not retroactively reduce a paid quota during its current cycle without a technical, legal, or security reason.
Beta, preview, or experimental features may change, fail, or be discontinued. Do not use them as the sole system for critical activities.
5. Trial, subscription, renewal, taxes, and refunds
The applicable trial, limits, and price are disclosed before purchase. After a trial expires, creation may be restricted until subscription; reading and export remain available until the deletion date shown in the app.
Paid subscriptions are processed by Stripe, billed on the selected cycle, and automatically renew until cancelled. You authorize clearly disclosed prices, taxes, and charges. Failed payments may be retried and paid features may be restricted after a cure period.
You can stop renewal through the billing portal. Unless stated otherwise, cancellation takes effect at the end of the paid period and does not delete your account. Price changes will be notified reasonably in advance and apply to a future cycle.
Refunds and withdrawal rights follow applicable law. Requests may be sent to suporte@myrna.app. Nothing here restricts mandatory consumer rights.
6. Your content and the operational license
You retain ownership of text, notes, data, references, responses, images, audio, PDFs, files, and other materials you submit or generate (“User Content”). We do not sell your Content or acquire ownership of it.
You grant us a non-exclusive, worldwide, royalty-free license, limited to the period necessary to host, technically copy, reformat, index, transmit, display, back up, and process Content solely to operate, secure, and provide the Service to you and people you authorize. It includes contracted service providers and ends upon deletion, subject to residual disaster-recovery copies and legal retention.
You represent that you have all rights and permissions needed for submitted content, including third-party personal data, research material, copyrighted works, and confidential information. You are responsible for legality, accuracy, integrity, and sharing permissions.
7. PDFs, attachments, and third-party material
The references module lets you store private PDFs within plan quota and locally extract metadata and bibliography. Uploading does not transfer copyright to myrna or make a file public by default.
Upload only files you created, licensed, lawfully obtained, or may legally store. You may not use the Service for piracy, distribute unauthorized copies, or bypass copyright controls.
We may limit size and type, reject invalid files, and remove or isolate malicious, unlawful, or validly reported material. Automated extraction may be incomplete; verify authorship, DOI, citations, and metadata before academic use.
8. Teams, collaboration, and permissions
People you authorize may view and, according to permissions, comment, edit, copy, or delete shared content. Collaborator changes may appear in history and remain in copies or exports they made.
Grant the least access needed and review members and permissions. The workspace or item owner controls primary access. Closing your account does not delete copies lawfully retained by other users or the responsible organization.
When an organization determines purposes and means for member data, it may be the controller and myrna its processor. Requests about organizational content may need to be directed to that organization.
9. Public links, forms, and third-party content
Notes, forms, and presentations become public only when publishing is enabled. Anyone with the link may access, copy, capture, redistribute, or index material outside our control. Revocation stops new access through myrna but cannot retrieve prior copies.
Public-form creators determine fields, purpose, and recipients. They must provide an appropriate privacy notice, collect only necessary data, obtain consent where required, and respond to rights requests. Do not request passwords, card data, authentication secrets, or sensitive data without necessity and safeguards.
We may investigate reports and restrict content under these Terms, the law, and our Report and Takedown Policy.
10. Acceptable use
You may not use, attempt to use, or help others use the Service to:
violate laws, court orders, intellectual property, privacy, data protection, image, reputation, confidentiality, or contractual rights;
publish child sexual abuse material, non-consensual intimate imagery, threats, harassment, fraud, hate, incitement to violence, or content that puts someone at risk;
send malware, destructive code, spam, phishing, deceptive material, or content designed to gain unauthorized access;
probe vulnerabilities without authorization, bypass authentication, permissions, quotas, or rate limits, or interfere with infrastructure;
scrape or automate access outside authorized APIs and limits, resell the Service, or use another person’s account or token;
reverse engineer or attempt to extract source code, models, or secrets except where expressly allowed by law;
impersonate others, fraudulently conceal content origin, or collect personal data without a legal basis;
use AI to facilitate unlawful content, fraud, discrimination, or high-risk activity without qualified human review.
We may impose technical limits, block requests, remove public content, or proportionately suspend accounts. Where practical and safe, we will explain the reason and allow correction or appeal.
11. Artificial intelligence features
AI is invoked at the user’s initiative. Writing, summarization, translation, OCR, transcription, and project or board generation send the prompt and necessary content to the configured provider. If a primary provider fails before responding, some requests may be sent to a configured fallback. The Privacy Policy identifies OpenAI, DeepSeek, and related international transfers.
Do not submit secrets, health data, children’s data, confidential information, or third-party personal data without authority and a legal basis. Vault content ceases to be end-to-end protected if you decrypt it and choose to send it to an external feature.
Outputs may be wrong, incomplete, biased, outdated, or similar to third-party content. Verify facts, calculations, authorship, citations, and licenses. AI is not medical, legal, financial, accounting, or other professional advice and must not alone make decisions with significant effects on people.
myrna does not claim ownership of generated output but does not guarantee exclusivity, protectability, or non-infringement. Use remains subject to provider rules and applicable law.
12. External services, integrations, and content
The Service may query or display content from Stripe, Google, OpenStreetMap, Open-Meteo, bibliographic databases, Openverse, Iconify, YouTube, Vimeo, and other services. They have independent terms, policies, availability, and accuracy.
Grant integrations only necessary permissions. Following a link, playing embedded media, or authorizing a provider may send technical data and action content directly to it. We may replace or discontinue an integration if its terms, security, or availability changes.
Bibliographic metadata and external results are informational. Verify original sources before citing, publishing, or deciding.
13. API, MCP, and automations
Personal API/MCP tokens let external tools act for you within granted scopes. The full token is shown only at creation; protect it like a password, grant minimum scope, and revoke it when no longer needed.
You are responsible for connected tools and their instructions, changes, or leaks. myrna may restrict or revoke tokens involved in abuse, security risk, or a Terms violation. Developers must disclose to end users how their data is handled.
14. myrna intellectual property and feedback
The Service, interface, brand, code, documentation, visual templates, and myrna-provided content belong to the operator or licensors and are protected by law and applicable software licenses. These Terms grant only a limited, revocable, non-exclusive, non-transferable right to use the Service while authorized.
We may use suggestions and feedback to improve the product without compensation, provided they do not include unnecessary confidential or personal data. Feedback does not transfer ownership of the rest of your Content.
We use proportionate safeguards, but no internet service eliminates all risk. Vault device-side encryption covers only content you explicitly lock; titles, metadata, sharing records, unprotected files, and other modules are not automatically end-to-end encrypted.
If you lose both the Vault passphrase and recovery key, locked content may be unrecoverable. We cannot reconstruct a key we do not possess. Keep it secure and never send it to support.
16. Availability, synchronization, and copies
We use reasonable efforts to keep the Service available and data preserved, but maintenance, network failure, sync conflict, supplier outages, and events beyond our control can occur. A local “pending” state means a change has not yet been confirmed by the server.
Use export tools and keep independent copies of irreplaceable material. Structured account exports may reference rather than embed attachments; separately download files you need. The Service is not an official recordkeeping, legal archive, medical record, or permanent-preservation repository.
17. Maintenance, changes, and discontinuation
We may fix, update, add, or remove features for security, compliance, and viability. Material reductions to paid functionality will be communicated reasonably in advance where possible.
If we discontinue the Service for business reasons, we will try to provide notice and a reasonable export window, unless law, security emergency, or technical impossibility prevents it. Mandatory refunds for paid but undelivered periods will be honored.
18. Suspension, termination, and data deletion
You may stop use, cancel a subscription, and delete the account in Settings. Cancelling does not itself delete the account. Account deletion starts permanent removal from the database and private file storage, subject to legal retention, security records, and residual disaster-recovery copies.
We may suspend or terminate access for non-payment, security risk, legal order, abuse, or material breach. We will try to give notice and cure time for remediable violations, but may act immediately for fraud, imminent harm, seriously unlawful content, or infrastructure threats.
Expired accounts may remain read-only until the deletion date displayed in the app. Export before that date. Shared content and organization-controlled responses may remain in other users’ copies or spaces under their legal basis.
19. Warranties and nature of the Service
To the extent permitted by law, the Service is provided as is and as available. We do not guarantee uninterrupted operation, compatibility with every device, perfect preservation of imported formatting, external metadata accuracy, or fitness for a particular professional purpose.
Nothing in these Terms excludes mandatory warranties or duties of quality, security, information, or redress, especially under consumer law.
20. Liability limits
Each party is liable for direct damage it causes under applicable law. To the lawful extent, we are not liable for unforeseeable indirect or consequential losses, independent third-party acts, user-submitted content, or decisions made without the review required by these Terms.
Any contractual limit is construed narrowly and does not apply to fraud, gross negligence, confidentiality or data-protection breach attributable to myrna, life or personal injury, refunds, consumer rights, or liability that law prohibits limiting.
For business users, where lawful, myrna’s aggregate Service-related liability is capped at the greater of fees paid in the preceding 12 months and any legally required minimum. This cap does not reduce consumer rights.
21. Third-party claims
If you use the Service commercially and your unlawful content or use causes a third-party claim against myrna, you must cooperate and reimburse costs and awards directly caused by your breach, to the extent allowed by law. This does not apply to consumers for facts attributable to the Service or to harm caused by myrna.
22. Events beyond reasonable control
Neither party is liable for delay caused by an unavoidable event beyond reasonable control, such as disaster, war, widespread power or telecommunications outage, large-scale attack, government act, or systemic supplier failure, provided reasonable mitigation is used. Due payment and data-protection duties remain.
23. Governing law and disputes
These Terms are governed by Brazilian law without displacing mandatory law in your country. Before filing a claim, contact suporte@myrna.app so we can seek a direct resolution.
Consumers retain access to consumer authorities and courts available under mandatory law, including their home forum where applicable. For business relationships without a mandatory venue, the courts at the operator’s address have jurisdiction.
24. Changes to these Terms
We may update these Terms for legal, security, provider, or product changes. The date above identifies the current version. Material changes will be announced in the app or through registered contact information before taking effect where required.
If a change requires renewed consent or acceptance, we will request an affirmative action. If you disagree, you may cancel and export before the effective date, subject to the purchased cycle and applicable law.
25. General provisions and contact
If a clause is invalid, the rest remains effective and the clause is construed to the closest lawful effect. Delay in enforcement is not waiver. You may not assign your account or these Terms without approval; we may transfer the contract in a corporate reorganization while preserving your rights and giving legally required notice.
