Privacy policy

1. Data controller

The data controller is Yiriwa LLC, publisher of Kaneme. Questions about personal data may be sent to info@kaneme.com.

Kaneme has its own processing activities, separate from those of other services published by Yiriwa LLC. Using Kaneme does not subscribe you to communications from another service.

2. Data processed

Kaneme processes three categories of data for distinct purposes.

• Account data: email address, name if provided, technical identifiers, and authentication methods. Purpose: create and secure access. Legal basis: performance of the contract.
• Content and voice profile: texts submitted by the customer, derived voice profile, produced documents, and saved sources. Purpose: provide the requested service. Legal basis: performance of the contract.
• Usage and billing data: completed operations, credits used, timestamps, technical logs, subscription history, and payment history. Purposes: billing, security, fraud prevention, and reliability improvement. Legal bases: performance of the contract, legal accounting obligations, and legitimate interests.

3. What Kaneme does not do with your texts

Texts submitted by a customer are used to build that customer’s own voice profile, and no other. They are not added to a training corpus shared among customers or used to train a model made available to third parties.

The measurement engine is never recalibrated on text produced by artificial intelligence, including text written with the help of the service. This rule protects both measurement integrity and content confidentiality.

Two public accountless tools coexist, and they do not process your text in the same way. The automation-marker reading (“check my voice”) is calculated in the browser: pasted text is not sent to our servers. The authorship verdict (“who wrote this text?”), by contrast, sends the text to our servers for the duration of the request because the measurement layer cannot run in a browser; the text is not stored, linked to an account, or reused, and disappears when the request ends.

Customer content is not sold, rented, or disclosed for advertising purposes.

4. Processors and transfers

Kaneme relies on technical providers acting as processors, each for a defined purpose and under a contractual confidentiality commitment.

Some providers are established outside the European Union. The corresponding transfers are governed by the European Commission’s standard contractual clauses or an equivalent mechanism.

• Database hosting and authentication: Supabase (data hosted in the European Union, Paris region).
• Application hosting and delivery: Cloudflare, Inc. (Workers network, United States).
• Artificial-intelligence model providers, to carry out requested operations: submitted content is not used to train their models under the contractual options selected.
• Calculation of style representations used for measurement: dedicated inference service on private infrastructure.
• Extraction of content from web addresses submitted to monitoring: a third-party page-reading service receives the requested address and retrieved page.
• Payment: Stripe (payment cards). No card data passes through our servers.
• Transactional email: Resend.
• Google account sign-in, when selected: Google receives the authentication request. This route is optional; email-link sign-in does not use it.
• Anti-bot protection for sign-in forms: Cloudflare receives your IP address and technical browser signals when the request is sent.
• Application error monitoring: Sentry receives the technical context of an incident, which may include your account identifier.

5. Retention periods

Content and the voice profile are retained while the account is active. They are deleted within thirty days after account deletion, unless a legal obligation requires otherwise.

Billing data is retained for the legally applicable accounting and tax period.

Technical and security logs are retained for no more than twelve months.

Audience-measurement events collected by Kaneme itself are deleted automatically after ninety days. They contain no account identifier.

Technical anomalies recorded by Kaneme on its own servers—error message and technical trace, without an account identifier or content you wrote—are deleted automatically after ninety days.

You may request deletion at any time, without closing the account, for content not required to satisfy a legal obligation.

6. Your rights

Data subjects have rights of access, rectification, erasure, restriction, objection, and portability, as well as the right to give instructions concerning their data after death.

You may exercise these rights by contacting info@kaneme.com. We respond within one month, which may be extended under the conditions permitted by applicable law.

Data subjects may also lodge a complaint with the competent supervisory authority in their country of residence.

7. Security

Data access is segregated by account at database level, not only in the application. API keys are stored in hashed form. Data is encrypted in transit.

Access tokens for third-party services connected by the customer are kept out of browser reach and used only on the server.

8. Cookies

Kaneme sets cookies that are strictly necessary for the service, including authentication-session cookies. These are secure, first-party cookies and are not shared with another domain.

Kaneme also measures its audience itself, without any cookie or identifier stored on your device. These measurements never leave our servers, are shared with no one, and are limited to the page viewed, device type, and referring site. Your IP address and browser are used only for the duration of the request to calculate a visitor key that changes every night; neither is retained, and the key cannot recognize you from one day to the next or on another site.

Kaneme uses no third-party audience-measurement service and sets no advertising or cross-site tracking technology.

The internal measurement described above does not require prior consent: it stores nothing on your device, follows no one across sites, and produces only totals. You may nevertheless disable it at any time, and that choice is respected.

Your choice is saved on the device you use. You may change it at any time using the control below without losing access to Kaneme.

9. Minors

The service is not intended for anyone under sixteen. We do not knowingly collect data from a minor under that age; if notified, we delete it without delay.
