A plain-language explanation of cookies and reader choices.

1. What cookies do

Cookies are small files or browser values that help a site remember a choice, maintain a session, or understand broad usage. Kalvin uses them carefully and does not use cookies to create a medical profile.

2. Essential preference

The cookieChoice value records whether a reader selected Accept or Reject in the banner. It may remain for 12 months and is used only to avoid repeatedly displaying the same choice.

3. Session functions

Temporary session identifiers, where needed by hosting or security services, may expire when the browser closes or within 24 hours. They support page delivery and abuse prevention.

4. Analytics

Optional analytics may measure page views, approximate region, device category, and referral source. Analytics identifiers may last up to 13 months and are reviewed in aggregate rather than used to identify a person.

5. Preferences

Preference storage can remember display or consent settings for up to 12 months. We avoid storing sensitive health information in cookies.

6. Third parties

Hosting, security, font delivery, and analytics providers may set technical values under their own policies. We select services with practical security controls and review their configuration.

7. Browser controls

Most browsers allow cookies to be blocked, deleted, or limited by site. Blocking essential values may change how the banner or pages behave, while rejecting optional analytics does not prevent normal reading.

8. Consent

The banner asks for a clear choice. Rejecting optional cookies is respected. You can change browser settings or contact Kalvin if you believe a choice has not been recorded correctly.

9. Retention

Consent records may be retained for 24 months. Technical security logs may be retained for 90 days. Aggregated statistics may be retained longer because they no longer directly identify a reader.

10. International processing

Some providers may process technical information outside Indonesia. Contractual and security safeguards are used where appropriate, and only limited information is shared for the service requested.

11. Contact and complaints

Questions can be sent to Jalan Melati 15, Menteng, Central Jakarta, Jakarta 10310, Indonesia, or +62 21 7890 1234. We aim to acknowledge requests within 10 business days.

12. Updates

This policy was reviewed on 12 October 2026. Any material change will be dated and explained on this page before it is applied.

Cookie names are kept limited to the functions described here. The consent preference may be stored as cookieChoice for up to 12 months; a temporary session value may last for a browser session or no more than 24 hours; and an optional analytics identifier, if enabled, may last for up to 13 months. Exact expiry can vary when a browser removes storage early, a user clears site data, or a security service rotates its identifier.

Essential values do not ordinarily contain a person’s name, email address, health information, or message contents. Analytics, where consented to, is configured to support broad measurement such as page path, approximate region, device category, referral source, and visit timing. Kalvin reviews aggregate reports and does not use cookie values to infer a reader’s medical condition or make decisions about access.

Consent is recorded separately from reading activity so that rejecting optional measurement does not prevent ordinary access to articles. A reader can withdraw or change a choice by clearing Kalvin site data, adjusting browser controls, or contacting the desk. A fresh choice may be requested after the 12-month consent period or when the consent mechanism materially changes.

Some infrastructure providers may process technical request data outside Indonesia. Their role is limited to hosting, delivery, security, or measurement under their own contractual and privacy obligations. A browser’s developer tools can show current storage values, but deleting a value does not delete correspondence or server logs; those records follow the retention periods described in the privacy policy.

Questions about cookies can be sent to Jalan Melati 15, Menteng, Central Jakarta, Jakarta 10310, Indonesia, or +62 21 7890 1234. Kalvin aims to acknowledge a cookie concern within 10 business days. This policy was reviewed on 12 October 2026 and will be updated with a new date when purposes, names, or lifespans materially change.

Cookie storage is limited to a technical purpose and is not intended to reveal a person’s name, health information, or message contents. A browser may store a small value locally while the corresponding server record, if any, follows the retention rules in the privacy policy. Clearing site data removes the browser value but does not automatically remove a previously submitted contact message. That distinction helps readers understand what each control can do.

The names used for ordinary functions include cookieChoice for consent, a temporary session identifier used by hosting or security infrastructure, and an optional analytics identifier where that service is enabled. The consent preference may last 12 months. A session value normally ends when the browser closes or within 24 hours, while an analytics identifier may last up to 13 months.

Analytics may record page path, approximate region, device category, referral source, and visit time in aggregate. It is not configured to infer a medical condition or create a personal wellness profile. A provider may process technical request data in another country, subject to its own safeguards and the service arrangement. Kalvin reviews whether optional measurement remains necessary and proportionate.

Readers can reject optional cookies in the banner, delete site data, use browser controls, or contact Kalvin if a recorded choice appears incorrect. Rejecting optional values does not prevent normal reading. Blocking essential values may cause the consent banner or session features to behave differently, which is a practical consequence of browser-level blocking rather than a requirement to accept analytics.

Consent records may be retained for up to 24 months so the choice is respected, while aggregate reports may be kept without direct identifiers. Questions can be sent to Jalan Melati 15, Menteng, Central Jakarta, Jakarta 10310, Indonesia, or +62 21 7890 1234. This policy was reviewed on 12 October 2026 and will record a new date when names, purposes, or lifespans materially change.
