What Are Cookies?
Cookies are small text files stored on your device when you visit our website. We use cookies to make the site work and — only with your explicit consent — to analyse traffic and support advertising. This policy documents every cookie our site currently sets, organised by GDPR category.
1. GDPR Cookie Categories
Under the General Data Protection Regulation (GDPR), cookies are divided into two groups: strictly necessary cookies that are required for the site to operate (no consent needed), and all other cookies that require your informed consent before they are activated. Our consent banner enforces this split on every page.
1.1 Strictly Necessary
Set automatically when you visit the site. They do not track you or collect data beyond what is needed to run the consent system itself.
- Consent required: No
- Can be disabled: No — disabling this cookie in your browser will cause the consent banner to reappear on every page visit
1.2 Analytics
Collect anonymous data about how visitors use the site. The tracking script is not loaded at all until you accept this category.
- Consent required: Yes
- Can be disabled: Yes — no site feature is affected
1.3 Marketing
Enable our advertising partner to measure campaign performance. The tracking script is not loaded at all until you accept this category.
- Consent required: Yes
- Can be disabled: Yes — you may see less relevant ads on other platforms
2. Every Cookie We Set
The table below is an exhaustive list of all cookies that our website places on your device. No other cookies or tracking scripts are loaded unless you give consent through our banner.
| Cookie Name | GDPR Category | Set By | Purpose | Duration |
|---|---|---|---|---|
| opto_cookie_consent | Strictly Necessary | Opto Softechs | Stores your consent choices (accept all, reject all, or per-category) so the consent banner does not reappear and your preferences are respected across every page. | 365 days |
| _ga | Analytics | Google Analytics | Distinguishes unique visitors so Google can build anonymous aggregate reports about site usage. | 2 years |
| _gid | Analytics | Google Analytics | Short-lived companion to _ga. Helps Google Analytics distinguish individual sessions within a 24-hour window. | 24 hours |
| _ga_<MEASUREMENT_ID> | Analytics | Google Analytics (GA4) | GA4 session cookie created automatically by the Google Analytics script. Tracks session duration alongside _ga. | 2 years |
| _fbp | Marketing | Facebook (Meta) Pixel | Facebook uses this cookie to attribute conversions and retarget users who visited our site via Meta ads on Facebook and Instagram. | 3 months |
3. Third-Party Services
Two third-party services are currently active on this site. Their scripts are loaded only after you accept the relevant cookie category — no third-party code runs before your consent.
3.1 Google Analytics
GDPR Category: Analytics | Cookies set: _ga, _gid, _ga_<MEASUREMENT_ID>
Google Analytics collects anonymous data about how visitors use the site — pages viewed, traffic sources, and session duration. The script (hosted at googletagmanager.com) is injected into the page only after you accept analytics cookies. You can also opt out site-wide using the Google Analytics Opt-out Browser Add-on.
Google Privacy Policy: privacy.google.com/policy
3.2 Facebook (Meta) Pixel
GDPR Category: Marketing | Cookie set: _fbp
The Meta Pixel measures how effectively our ads perform on Facebook and Instagram by recording conversion events on our site. The script (hosted at connect.facebook.net) is injected into the page only after you accept marketing cookies. You can manage your ad preferences on Meta directly.

4. How to Manage Cookies
4.1 Our Consent Tool
A consent banner appears on your first visit. You can accept all cookies, reject all non-essential cookies, or choose each category individually. You can revisit and change these choices at any time by clicking Cookie Settings in the footer of every page.
4.2 Browser Settings
You can also block or delete cookies directly in your browser:
- Chrome: Settings > Privacy and Security > Cookies and other site data
- Firefox: Options > Privacy & Security > Cookies and Site Data
- Safari: Preferences > Privacy > Manage Website Data
- Edge: Settings > Cookies and site permissions
4.3 Third-Party Opt-Out
- Google Analytics: Google Analytics Opt-out Browser Add-on
- Facebook / Meta: Manage ad preferences at facebook.com/adpreferences
5. Impact of Disabling Cookies
5.1 Strictly Necessary
These cannot be turned off through our consent tool. If you block them in your browser, the consent banner will reappear on every visit because we have no way to remember your previous choice.
5.2 Analytics
Turning off analytics cookies means we cannot collect usage data to improve the site. No feature you use will be affected in any way.
5.3 Marketing
Turning off marketing cookies means Facebook and Meta cannot attribute conversions to their ad campaigns. You may still see ads from us on other platforms, but they will be less targeted.
6. Your Rights Under GDPR (EU / EEA)
If you are in the European Union or European Economic Area, the GDPR gives you the following rights regarding cookies and any personal data they process:
- Right to informed consent: Non-essential cookies are activated only after you give clear, freely given, and specific consent.
- Right to withdraw consent: You can withdraw at any time via Cookie Settings in the footer. Withdrawal is as straightforward as giving consent.
- Right to object: You may object to cookie-based processing by using our consent tool or your browser controls.
- Right to erasure: You can request deletion of any personal data we hold that was collected through cookies by contacting us.
- Right to lodge a complaint: If you believe your rights have been violated, you may file a complaint with your national Data Protection Authority.
7. Updates to This Policy
We update this Cookie Policy whenever we add, remove, or change the cookies we use. The "Last Updated" date at the top of this page reflects the most recent change. We encourage you to review this policy from time to time.
