Privacy and responsible use

Privacy Policy and Terms of Use

Updated on March 29, 2026. This is the initial legal page for iScrev Notes, built to reflect the project as it exists today: a calm web-based notebook and journal app where notes, formulas and handwriting are stored primarily inside the user’s own browser.

iScrev Notes was designed to keep content as close as possible to the user. For that reason, the basic use of the app does not require account creation, sign-up or mandatory submission of personal data to a central project database.

During normal use, entries, handwriting strokes and editor preferences remain stored mainly in the user’s own browser, through local technologies such as IndexedDB and, when needed, localStorage. In practical terms, this means the project’s own server does not ordinarily receive or maintain the personal diary content in its own database.

At the same time, the site depends on a few external technical resources, such as Google Fonts, jsDelivr and KaTeX, and it may display Google AdSense ads. This page explains those layers clearly, taking into account privacy laws, international transparency expectations and Google advertising requirements.

  • Current responsible party WSRicardo, public author and maintainer of the iScrev Notes project.
  • Scope Institutional pages, public pages and the web application available at diario.html.
  • No required account iScrev Notes does not require login, account creation or mandatory user registration for its basic app flow.
  • Contact path Privacy or usage requests can be sent to [email protected] or through the contact page.

Privacy Policy

What data may be processed

iScrev Notes aims to operate with minimal data handling. Even so, some information may still be involved so the site can load correctly, preserve local notes, use external resources and display advertising when available.

Local browser data

Entries, pen strokes, active language and editor preferences are stored mainly in IndexedDB and, when needed, localStorage, inside the user’s own browser.

Technical access data

As with most websites, hosting, CDN, font loading and library providers may process IP address, date, browser, operating system and request metadata to deliver the page correctly.

Cookies and advertising

The site may display Google AdSense ads. In that case, Google and its partners may use cookies, local storage and similar technologies to deliver, measure and, when permitted, personalize ads based on visits to this and other websites.

Purposes, legal grounds and user rights

Local data exists to provide the service requested by the user: open entries, save content, restore sessions, remember language choices and support export flows. Technical navigation data may also be processed for security, compatibility, abuse prevention, resource delivery and advertising display.

When applicable, data handling should rely on appropriate legal grounds, especially service execution, legitimate interests compatible with security and operation, legal obligations and consent whenever optional advertising or preference technologies specifically require it.

For users in jurisdictions where prior consent is required for advertising technologies, the site should use a compatible consent mechanism before such technologies are activated, in accordance with applicable law.

Google’s advertising cookies may enable Google and its partners to show ads based on a user’s visits to this site and/or other sites on the internet, always subject to the applicable legal framework and the user’s consent or preference choices.

  • Right to confirmation, access and correction of personal data being processed.
  • Right to request anonymization, blocking or deletion when applicable under the relevant law.
  • Right to receive information about sharing, applicable legal grounds and consent withdrawal when relevant.
  • Right to object to irregular processing and request clarification about retention and security.
  • Project server As a rule, the diary content is not stored on the project’s own server during the normal use of the app.
  • Voluntary contact If a user sends an email, the project may process the sender’s name, email address and message content in order to reply.
  • Third parties and ads The project may technically rely on Google Fonts, jsDelivr, KaTeX and Google AdSense for interface resources, math rendering and monetization.
  • International transfers Some of those providers may operate infrastructure outside Brazil, which may involve international processing or transfer of technical request data.
  • Retention Local entries remain in the browser until the user deletes them, clears browser storage or removes them manually inside the app; contact messages may be kept for the time reasonably necessary to answer the request and comply with legal obligations.
Users can manage ad preferences in Google’s Ads Settings at adssettings.google.com. They can also control cookies and local storage in their browser settings and, where available, use additional industry opt-out tools offered by third parties, such as aboutads.info. If analytics, login, remote sync or form flows are added later, this page should be revised accordingly.

Terms of Use

Basic rules for using iScrev Notes

The terms below summarize the expected use of the application and clarify what the service offers, what depends on the user and what may evolve as the project grows.

Use 01

Permitted use

The app may be used for study, writing, personal organization, research, drafting and other legitimate productivity activities.

Use 02

User content

The user remains responsible for the content created, imported, exported or shared from within the application.

Use 03

Service continuity

The project may be updated, corrected, paused or changed over time, without a guarantee of uninterrupted availability.

Use 04

Third-party services

Fonts, libraries and CDNs used by the site follow their own policies and technical terms alongside this page.

Responsibility, backup and practical limits

iScrev Notes is provided as a lightweight web tool in continuous evolution. Users should keep backups of important content, especially if they intend to clear browser data, switch devices or rely solely on local storage.

The service may not be used for unlawful, abusive, fraudulent, offensive or disruptive activities, including attempts to compromise the integrity of the site, its resources or other users' experience.

The project’s design, code and identity remain protected by applicable intellectual property rules, without prejudice to the open-source licenses of third-party libraries used in development.

  • Exported files When a user exports Markdown or PDF, responsibility for storing, sharing and handling those files belongs to the user.
  • No professional advice The app does not replace legal, medical, accounting or specialized professional guidance.
  • Updates Continued use after meaningful changes indicates awareness of the current version of this page, subject to applicable rights.
  • Minors If children or teenagers use the app, supervision by a responsible adult is recommended whenever appropriate.

Exercising rights and next steps

How to request information, corrections or deletion

Under applicable privacy laws, data subjects may request information about personal data processing, including confirmation of processing, access, correction, anonymization, blocking, deletion, objection and clarification about sharing, whenever those rights apply.

Requests related to data effectively controlled by the project, such as emails received or contact records that may be maintained by the responsible party, can be sent to [email protected] or through the contact page.

It is important to note, however, that the diary content, handwriting strokes and much of the app’s preferences remain stored locally in the user’s own browser, without ordinary transmission to the project’s own server. In those cases, the responsible party may not have technical access to such data and therefore may not be able to remotely view, modify or delete information that exists only on the user’s device.

For data kept only in the browser, users can exercise direct control themselves, for example by deleting entries inside the app, exporting content before removal or clearing browser and device storage.

Whenever data under the project’s direct control is involved, requests will be reviewed and answered within a reasonable time and according to applicable law. If the data subject believes the request was not handled properly, they may also seek the competent supervisory or legal channels available in their jurisdiction.

  • Support page Contact
  • Helpful information in a request Name, reply contact details and an objective description of the request.
  • Important limitation Data stored exclusively in the user’s browser may depend on direct action by the user on their own device.
