This policy applies to the LETROU, at letrou.com.br, administered by Francisco Alves Silva. It explains the processing of data during navigation, the use of tools, contributions and service. The channel for privacy matters is the contact form, in the subject “Privacy and personal data”.
1. Data we can handle
Browsing and security: pages accessed, usage events, searches, date and time, technical failures and session identifiers. The technical report can register error codes, used engine, response status, script file and error line, browser and screen size; it does not include audio or lyrics text. The server and security services can also register IP address and browser information. These data help prevent abuse, keep the site stable and understand which features are used.
Forms: name, e-mail, subject and message. Remove requests include the URL of the content, the work, the requester's relationship with the rights and verification elements provided. They are used to analyze, answer and document the service, not to publish a list of applicants.
Account and contributions: when you use an account, WordPress handles the registration and authentication data. Lyrics, titles, artists, corrections and other materials sent for review can be stored and, if approved, published. Do not include phone, address, email or third party information within a contribution to the public.
2. Audios, links and microphone usage
An audio or link sent to the transcription tool is used to perform the requested processing. Depending on the configuration, the file or material obtained from the link is forwarded to a transcription provider. The result and information of the operation may be recorded for operation and monitoring of the service. When the system gets title, artist and lyrics under valid conditions, the result can be published automatically and remains subject to correction, administrative review and eventual withdrawal.
Temporary files used in processing do not form a public audio library. Logs, backups, and vendor records may have their own deadlines. Avoid sending confidential recordings, sensitive data or material that you are not allowed to use.
The tuning monitor and the vocal explorer ask for access to the microphone by the browser to analyze the sound on the device. These features do not record or send audio to the transcription service. Permission can be revoked in browser settings.
3. Personal editions, repertoires and links
Its editions of lyrics, short titles, repertoire order and preferences are stored in the browser. Lyrics can also be prepared in the storage of the device to speed up the exchange in Stage Mode. These features do not alter the public version of a song.
When generating a shareable link, you request that a copy of the lyrics and order chosen be stored on the server. The link is not listed in the catalog or intended for indexing; however, anyone who receives it can access and save a copy. Do not include personal data or confidential content in editions. The link can be deleted by the link controls on the device that created it or by administration. The deletion does not collect copies already saved by other people.
4. Cookies, advertising and storage on the apparatus
We may use cookies essential for authentication and functioning of WordPress. Preferences such as theme, repertoire and read adjustments can be stored in the browser's local storage. Removing the data from the site can remove these preferences and the repertoire saved on this device.
If Google AdSense or any other advertising service is activated, Google and authorized partners may use cookies, IP addresses and other identifiers to convey, measure and protect ads, in accordance with the applicable consent settings and policies of their respective services. When required for a particular region or technology, LETROU must present consent controls before using non-essential storage.
You can control cookies, permissions and storage in your browser settings. Blocking essential features can affect login and some functions. Additional measurement, advertising and integration resources depend on the active configuration of the site.
YouTube videos: the site can seek videos by the title and artist of the song and incorporate the corresponding player. The query is performed by the server; by loading the player, your browser connects to YouTube/Google, which can receive IP and technical information according to your own policies. The playback depends on the availability of the video and the rules of the service.
5. Suppliers and sharing
Hosting, sending e-mail, security, transcription services and other integrations receive the necessary data to provide their services. LETROU-compatible transcription providers include Deepgram, Gemini/Google, Cloudflare, AssemblyAI and Speechmatics; only those configured for the operation are used. Links may also involve a service responsible for obtaining the audio allowed.
These suppliers can process data outside Brazil. The processing shall be subject to the conditions of each service and to the applicable requirements on data protection and international transfers. Data may also be shared when necessary to comply with legal obligation, meet competent authority or safeguard rights in a procedure.
If external advertising or measurement services are activated, they may use cookies and other identifiers according to their configuration, policy and consent requirements. This policy alone does not authorize unrestricted tracking.
6. Reasons and limits of treatment
We treat data to provide the requested services, meet messages, administer contributions, protect the functioning of the site and comply with legal obligations. According to the purpose and the case, treatment may be based on the performance of contracts or related procedures, in the legitimate interest subject to the assessment of the rights of the holder, in compliance with legal obligation, in the regular exercise of rights or in consent when required. The science of politics is not a general authorization for any use of your data.
7. Conservation and safety
Records are kept for the time required for the purpose, service and applicable obligations. Requests may remain registered to prove the analysis and the measure adopted; completed care data may be eliminated by the administration when no longer necessary. Minimum information to prevent the republishment of a withdrawn lyrics may be kept separately.
Access to applications is restricted to administrators. We use access controls and security measures compatible with the service, but no system eliminates all risk. Backups and vendors can save data for their own cycles, even after their deletion from the active area of the site.
