Terms of Use

Version 1 · effective October 24, 2026 · This is a translation. If it differs from the Portuguese version, the Portuguese version prevails.

1. Acceptance

These Terms govern the use of Tiska (tiska.app), a service provided by Leeway Consultoria e Tecnologia Ltda., a Brazilian company, CNPJ 61.738.333/0001-07, located at Rua Pais Leme, 215, suite 1713, Pinheiros, São Paulo/SP, 05424-150, Brazil (“Leeway”, “we”).

By creating an account or using Tiska, you agree to these Terms and to the Privacy Policy. If you use Tiska on behalf of an organization, you represent that you are authorized to accept them for it. A specific agreement signed with the organization prevails over these Terms where they differ.

2. What Tiska is

Tiska is a professional memory: it receives the content you choose to send, extracts knowledge from it (people, organizations, projects, decisions, facts and how they relate), keeps that knowledge organized over time, and serves it to the AI assistants you connect, with the source of each piece of information.

Tiska is not a document manager, a backup service or an archive of originals: it keeps the extracted knowledge and a text representation of each item, not exact copies of your files. Keep your originals where they already are.

3. Account and access

• You must be 18 or older.
• Access may require an invitation or approval from Leeway or your organization.
• Account information must be accurate and up to date.
• You are responsible for keeping your credentials secret and for the access you grant to AI assistants and other tools, which can read and write to your brain. Revoke any access you do not recognize and tell us about misuse.

4. Your content

• The content is yours. You keep all rights to what you send and to the knowledge generated from it.
• You grant Leeway a limited, non-exclusive, royalty-free license only to store, process, transform and display that content as needed to provide the service to you, including through the providers described in the Privacy Policy. This license ends when the content is deleted.
• We do not use your content to train AI models.
• Your knowledge is kept in an open format and you can take it with you.
• When you use Tiska through an organization, it may set its own rules on ownership, access and retention of the content, which prevail in that relationship.

5. Acceptable use

You are responsible for the content you send and confirm that you have the right to send it, including when it contains other people's personal data or third parties' confidential information. You may not:

• send unlawful content or content that violates other people's rights, such as privacy, intellectual property or professional secrecy;
• use Tiska to monitor, stalk or discriminate against people;
• try to access other users' data, test vulnerabilities without authorization, bypass usage or cost limits, or overload the service;
• copy, reverse engineer or resell the service without authorization;
• embed instructions in content intended to manipulate the AI against other users or the service.

6. AI limitations

Tiska uses AI models, which can be wrong, leave things out or misread information. Tiska shows the source of each piece of information and should not claim what it did not keep, but you should check anything important before acting on it. Tiska does not provide legal, medical, financial or other regulated professional advice.

7. Third-party services

Tiska connects to services you choose, such as AI assistants, sign-in providers, content sources, GitHub repositories and AI providers used with your own key. Those services are governed by their own terms, and Leeway is not responsible for them. Data you tell Tiska to deliver to one of those services becomes subject to its rules.

8. Credits and billing

• Tiska is paid for with prepaid credit in US dollars (US$). Credit is bought in Brazilian reais and converted at the Central Bank of Brazil PTAX rate on the day of purchase.
• Each AI use debits from your credit the processing cost plus a platform fee, shown before purchase.
• When the balance reaches zero, processing pauses until you buy more. None of your content is deleted for lack of balance.
• There is a monthly cost cap per brain to avoid unexpected spending.
• If you use your own key with an AI provider, you pay the model cost directly to that provider, and Leeway charges only the platform fee on a monthly invoice.
• Payments are processed by Stripe. Leeway does not store card details.
• Refunds: you may request a refund of unused credit within 7 days of purchase. After that, credit is non-refundable, but it does not expire.
• Prices and fees may change with advance notice. Changes do not affect credit already purchased.
• Taxes are included or added as shown at purchase.

9. Availability and changes

Tiska is continuously evolving. We will do our best to keep it available and secure, but we do not guarantee uninterrupted or error-free operation. We may add, change or remove features; when a change significantly affects what you use, we will give reasonable advance notice.

10. Suspension and termination

• You may close your account at any time by writing to dpo@getleeway.co or, once the option is available, in Tiska.
• We may suspend or close accounts that violate these Terms or the law, or that put the service or other users at risk. Whenever possible, we will warn you first and give you a chance to fix the issue.
• After closure, you will have 30 days to export your knowledge, unless the law or the risk involved prevents it. After that, data is deleted as described in the Privacy Policy.

11. Intellectual property

The software, the Tiska brand, the design and the documentation of the service belong to Leeway or its licensors. These Terms do not give you any rights to them beyond using the service. Suggestions you send us may be used to improve Tiska without any obligation to compensate you.

12. Liability

• The service is provided as is, to the extent permitted by law.
• Leeway is not liable for decisions made on information from Tiska without proper checking, for content sent by users, for third-party services you connect, or for lost profits or indirect damages.
• Where Leeway is liable, its liability is limited to the total you paid in the 12 months before the event.
• Nothing in these Terms removes rights granted by the Brazilian Consumer Protection Code or other mandatory consumer law, where applicable, or limits liability for willful misconduct.

13. Changes to these terms

We may update these Terms. Each version shows its effective date at the top. We will give advance notice of significant changes by email or in Tiska. If you keep using Tiska after the effective date, the new terms apply; if you do not agree, you may close your account.

14. Governing law and venue

These Terms are governed by the laws of Brazil. The courts of the City of São Paulo/SP have jurisdiction, without prejudice to a consumer's right to sue in the courts where they live.
