Cookie Policy

1. Cookies and local storage

Cookies are small data files stored by a website in your browser. localStorage and sessionStorage are browser storage mechanisms with similar uses. They can remember essential state, preferences or consent choices, and may also be used for analytics or advertising depending on the technology actually integrated.

2. Current storage inventory

opo_cookie_choices_v3Essential

Location: localStorage

Purpose: stores all four manually confirmed choices in one complete record. Kept until site data is cleared or choices are updated.

opo_*_consent_v1 / opo_*_consent_v1_manual_v2Legacy

Earlier analytics, marketing, meta and tiktok records are read only when no new record exists. Legacy refusals remain effective; allowances without manual confirmation require reconfirmation. Saving now writes only the new complete record.

_ga / _ga_M6DECKFJSTOptional analytics

Provider: Google Analytics 4

Purpose: distinguishes browser visits and records sessions and page use.

Duration: configured for 30 days, renewed on subsequent visits with consent; browser restrictions may shorten this period.

Essential cookies used by hosting or security providers still require verification. Local development previews do not send data to the production GA4 property.

3. Categories and activation

• Essential storage: supports security, network delivery and the notice state, within what is necessary to provide the website.
• Preference storage: remembers language, theme or display choices; not currently enabled.
• Analytics cookies: measure visits; enabled only after you manually save allowance and can be turned off in Cookie settings.
• Advertising cookies: support X advertising attribution, Meta page-view and download-click measurement or TikTok visit measurement; enabled only after you manually save allowance and can be turned off separately.

4. Third-party services

When the relevant setting is allowed, Google, X, Meta or TikTok may receive page URLs, referring pages, browser and device information, visit events, cookie identifiers, IP addresses and technical request information. Processing may take place outside your country. See the Google Privacy Policy, X Privacy Policy and Meta Privacy Policy. Other external services apply their own policies; this website cannot manage their cookies.

5. How to manage storage

“Cookie settings” in the footer shows your saved choices without resetting them or changing active measurement. Changes take effect when you select Save choices; Essential only immediately turns off all optional measurement. We attempt to clear this property’s analytics and advertising cookies; you can also delete site data in your browser. Withdrawal does not delete data already sent. If local storage is blocked, choices may not be saved. Failed saves do not enable new measurement; the notice stays open with retry guidance. Allow site storage and retry. If saving still fails, close all tabs for this website and clear site data before returning; other tabs may still use previous settings.

6. Manual confirmation and withdrawal

The four options may start selected, but a checkmark neither enables measurement nor saves permission. Click Save choices to save and enable the selected measurement. Browsing and downloads remain available before saving. Legacy allowance settings require one-time reconfirmation; legacy refusals are preserved. You can turn each one off at any time in the footer’s Cookie settings, or select Essential only. Disabling a setting does not affect browsing or downloads, and a previously disabled setting is not automatically restored on a later visit.

7. Updates

When a storage name, purpose, duration or third-party provider materially changes, this page will be updated and the notice or consent request will be shown again where required.

8. Contact

For Cookie or privacy questions or complaints, email opotrx@gmail.com or use the official support link listed on the website.

Optional X advertising tracking

X advertising tracking starts only after you select it and click Save choices. It measures visits and clicks on available app download links for advertising attribution; a click does not confirm installation. Opening the download menu does not send a download event. You can withdraw X tracking independently in Cookie settings.

The essential localStorage key opo_cookie_choices_v3 remembers your choice until you reset it or clear site data. With consent, X may process click identifiers (twclid), cookie identifiers, browser/device and technical request information, including IP addresses. X may use first-party _twclid and third-party cookies according to its own retention policy and browser restrictions. Processing may occur outside your country. We hide the page location from the pixel and do not attach wallet addresses, balances, email addresses or order details to events.

Choices are not saved automatically. Legacy allowance settings require one-time reconfirmation; previously declined choices stay declined. You can uncheck any option or select Essential only; browsing and downloads remain available. Cookie settings shows the saved choices without changing them. Saving X as off or selecting Essential only withdraws permission. If X has loaded, the page refreshes to unload it and we attempt to clear its first-party cookies. Already transmitted data and X-domain cookies cannot be deleted by this website. Local previews do not load the production pixel.

Optional Meta page-view and download-click measurement

Meta page-view and download-click measurement starts only after you select it and click Save choices. Meta Pixel 1639575114242429 sends PageView when you visit a page, including when navigating within the site. Clicking an available app download link sends the custom OPO_Download event once. Opening the download menu, page visits and refreshes do not send OPO_Download. A click does not confirm installation. We do not configure advanced matching or automatic event detection. You can withdraw Meta independently in Cookie settings.

The essential localStorage key opo_cookie_choices_v3 saves your choice until you reset it or clear site data. With consent, Meta may receive page URLs, referrers, browser/device information, cookie identifiers and IP addresses, and may process data abroad. Meta may set _fbp and _fbc cookies. We do not add wallet addresses, balances, email addresses or order details to events. Do not put private information in page URLs.

You can refuse Meta independently or withdraw consent in Cookie settings. We stop further measurement and attempt to clear first-party Meta cookies; this does not erase previously sent data or Meta-domain cookies. No tracking image is loaded without JavaScript. Local previews never send production pixel data.

TikTok visit measurement

TikTok Pixel OPO (DATSGM3C77U5PB60FCVG) is optional visit measurement. It starts only after you select TikTok and click Save choices. Legacy allowance settings require one-time reconfirmation. A previously saved refusal is not overridden. It loads only on the official domain while the saved setting is enabled. You can turn it off in Cookie settings or select Essential only. Local previews do not send production TikTok events.

The necessary localStorage key opo_cookie_choices_v3 stores your choice until reset or site data is cleared. With consent, TikTok may receive page URLs, referrers, browser/device information, IP addresses and cookie identifiers, and process them abroad. Advertising cookies may include _ttp, ttclid and ttcsid / ttcsid_<pixel code>, with a provider-specified duration of up to 13 months since last use. Withdrawal stops subsequent sharing and attempts to clear first-party TikTok cookies; it does not delete data already sent or third-party cookies.

This integration installs the base visit measurement only. It does not send registration, purchase or download-click conversions, call identify, or add phone numbers, email addresses, wallet balances or order details. Visits do not prove an app install or backend registration. Do not put private information in page URLs.
