Privacy Policy

Policy last updated: 11/11/2026
Cookie and service list last updated: 09/11/2026

This policy explains what personal information this website collects about you, why we collect it, who else receives it, and what choices and rights you have. It applies to this website (sentinel-watch.org) and to the Sentinel Watch app (app.sentinel-watch.org), including what we do with Google user data when you sign in with Google.

Who we are

This website is run by the organisation named below. That organisation is responsible for the personal information described in this policy.

Sentinel Watch Limited
The L. Plaza, 367 - 375 Queen's Road Central
Unit 1603, 16th Floor
NA Hong Kong

What personal information we collect

When you visit this website, our web server automatically records technical details that your browser sends with every request, such as your IP address, which pages you asked for, when you asked for them, and which page or search sent you here. This happens on every website, and we use it to serve pages and to keep the site secure.

Cookies and similar technologies may collect more than this, depending on the choices you make. That is described further below.

Information you give us

  • Customer accounts (shop owners and organisations): your name, email address, username and password (stored in encrypted form), your company name, and the locations and cameras you register. We use this to run your account and the services you use.
  • Orders and billing: your name, email address, billing address, tax details if you give them, and what you bought. Payments are handled by our payment processor through SureCart. We never see or store your full card number.
  • Watcher accounts in the Sentinel Watch app: your email address, username, chosen avatar, and your activity on the platform, such as hours on duty, attention checks, reports, Tribunal votes, Reputation Points and Sentinos balance. When you request a payout, we also collect the payout details needed to pay you, such as your PromptPay ID.
  • Google account information, if you sign in with Google: see the next section.
  • Contact and application forms: your name, email address, message and anything else you choose to send us, such as documents with a nonprofit application. Files uploaded through our forms are sent to us by email and are not stored on the website server.
  • Newsletter: your email address, your name if you give it, and which lists you joined. Every email has an unsubscribe link.
  • Camera footage: shops that use Sentinel Watch stream camera images to our Watchers. Faces and licence plates are blurred inside the shop before any stream leaves it. When a Watcher raises an alarm, a short clip of the blurred footage is shown to other Watchers in the Tribunal so they can confirm it. Watchers are not allowed to record or share what they see.

Google user data: how we access, use, store, share and protect it

You can sign in to the Sentinel Watch website and the Sentinel Watch app with your Google account ("Sign in with Google"). This section explains exactly what Google user data we receive and what we do with it.

What we access. When you sign in with Google, we request only the basic sign-in permissions: openid, email and profile. Google then shares with us your name, your email address, your profile picture and your Google account ID. We do not request or receive access to your Gmail, Google Drive, contacts, calendar or any other Google service or data.

How we use it. We use this information only to create your Sentinel Watch account, to sign you in, to recognise you when you return, and to show your name and picture inside your account. We do not use Google user data for advertising, we do not sell it, and we do not use it to develop, improve or train AI or machine-learning models.

How we store it. Your name, email address, profile picture link and Google account ID are stored in our account databases: the WordPress database of this website, hosted by Rocket.net, and Google Firebase for the Sentinel Watch app.

How we share, transfer or disclose it. We do not share, transfer or disclose Google user data to third parties, except to the service providers that host our website, sign-in and app on our behalf (Rocket.net and Google Firebase), or when the law requires us to. These providers may only use it to provide their service to us. We never sell Google user data or transfer it to data brokers or advertisers.

How we protect it. We protect Google user data and other personal information with these measures:

  • Encryption in transit: all traffic to the website and the app uses HTTPS (TLS).
  • Encryption at rest: data in Google Firebase and Google Cloud is encrypted at rest. Passwords are never stored in readable form, only as secure hashes.
  • Access control: only the people who need it to run the service can access personal data, through individual accounts with restricted permissions.
  • Protected secrets and signed requests: keys and passwords used by our systems are kept in Google Secret Manager, and requests between the app and the website are cryptographically signed.
  • Data minimisation: we only request the basic Google sign-in permissions and only keep what is needed to run your account.
  • Retention and deletion: we keep Google user data only while your account is open, as described below.

Limited Use. Sentinel Watch’s use and transfer of information received from Google APIs to any other app will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

Retention, removing access and deleting your data. We keep your Google user data for as long as your account is open, and delete it within 90 days after you close your account. You can remove Sentinel Watch’s access at any time in your Google Account, under Security, Third-party apps and services. To have your account and the Google user data we hold deleted sooner, contact us using the details at the bottom of this page. We will delete it within 30 days of your request, except records the law requires us to keep.

Cookies and similar technologies

Cookies are small files a website asks your browser to store. Similar technologies, such as pixels, tags and browser storage, do the same job in a different way. Some are needed for the site to work at all. Others are used for measurement or advertising, and those are the ones you get a choice about.

  • Essential Cookies Required for basic website functionality.
  • Functional Cookies Enable features like saved preferences and personalized content.
  • Analytics Cookies Measure how this site is used, such as which pages are viewed and where visitors arrive from. Also called reach measurement.
  • Marketing Cookies Used to show you relevant ads based on your interests.

Non-essential cookies are only set after you allow them through the cookie banner.

See the full list of cookies used on this site

You can review or change your choice at any time using the cookie preferences control on this site.

Your cookie consent choices

When you choose which cookies to allow, this site stores that choice in two cookies in your browser. surecookie_user_consent holds the choice itself and lasts 365 days. surecookie_session_id holds a randomly generated identifier and lasts 365 days regardless of that setting; it is created the first time you load a page, before you have chosen anything, so that a choice you make later can be matched to the same browser.

We also keep a record of the choice on this site, so that we can show, if we are ever asked, that you were given a choice and what you chose. Each record holds the date and time, which categories you allowed and which you refused, the random identifier from the cookie above, a shortened form of your IP address, and the country your visit appeared to come from. If you were signed in, it also holds your user account ID.

The IP address in the record is shortened before it is stored: for a normal IPv4 address the last part is replaced with a zero. We do not store your full IP address in these records, and there is no setting that would make us.

To work out which country your visit came from, this site sends your full IP address to a geolocation service operated by Brainstorm Force, the maker of the consent tool used on this site, at library.surecookie.com. The address is sent as part of the web address of that request, only the country comes back, and only the shortened address is stored here. That service is hosted in Germany. Requests reach it through a content delivery network run by a company based in the United States, so that step can involve a transfer outside the European Economic Area. The result is cached for 24 hours, so a repeat visit within that time does not send it again.

These records are stored on this website and are deleted automatically once they are 365 days old.

Separately from how long that record is kept, the choice saved in your browser lasts 365 days. After that it expires and you will be asked again. If we ever need to ask everyone again sooner, for example because the categories on this site have changed, the banner will reappear and your previous choice stops applying.

These consent records are not covered by the personal-data erasure tool built into this site. Erasing your other data leaves the consent record in place, because it is the evidence that you were given a choice. If you want the record itself removed, ask us and we will remove it by hand.

You can change or withdraw your choice at any time using the cookie preferences control on this site. Withdrawing does not undo anything that happened while your permission was in place.

Who receives information about your visit

Some of the services this site uses receive information about you directly, because your browser has to contact them to load the content or the script they provide. When that happens they can see your IP address and basic details about your browser, whether or not you interact with anything.

What this site sends from its own server

Separately from the files your browser loads, this site sends a small amount of information to other services from its own server while handling your visit. Because this happens on our side, your browser settings cannot control it.

  • Your IP address is sent to library.surecookie.com to work out which country you are visiting from, so the right consent rules can be applied and recorded. Only the country comes back.
  • The addresses of pages on this site are sent to our cookie scanning service on a schedule, so the cookie list above stays current. This is information about the site, not about you.

Other organisations that process information for us

These organisations process personal information on our behalf to run the website and the app. They may only use it to provide their service to us.

  • Rocket.net: website hosting.
  • Cloudflare: content delivery and protection against attacks.
  • SureCart and our payment processor: checkout, payments, invoices and subscriptions.
  • Google (Firebase and Google Cloud): sign-in, database and hosting for the Sentinel Watch app.
  • Coinbase: a digital wallet is created for each Watcher account through Coinbase’s wallet service, which receives your email address for this purpose. Google user data other than your email address is not shared with Coinbase.
  • Our email delivery service: account emails, order confirmations and newsletters.
  • Banks and payment providers in Thailand (PromptPay): sending payouts to Watchers.
  • Discord: only if you choose to join our community server. Discord’s own privacy policy applies there.

This site applies the same cookie and privacy practices to every visitor, wherever they are.

How long we keep your information

We keep personal information only for as long as we need it for the purpose we collected it for, or for as long as the law requires us to. How long this site keeps records of your cookie choices is set out under "Your cookie consent choices" above.

  • Accounts (customer and Watcher, including Google user data from Sign in with Google): for as long as your account is open. After you close it, we delete or anonymise your details within 90 days.
  • Orders, invoices and payout records: for 7 years, as required for business records under Hong Kong law.
  • Watcher activity (hours, reports, Tribunal votes, Reputation Points, Sentinos): for as long as your account is open, then deleted or anonymised.
  • Alarm clips reviewed in the Tribunal: only as long as needed to review the report and handle any follow-up, then deleted.
  • Form messages and applications: up to 2 years, or longer while we have an ongoing relationship with you.
  • Newsletter: until you unsubscribe.

Where your information is processed

We are based in Hong Kong. Some of the services listed above process information in other countries.

Where personal information is transferred out of your region, we rely on the following safeguard: European Commission Standard Contractual Clauses (SCCs), incorporated into our data processing agreement with our US hosting provider.

Your rights under the GDPR

If you are in the European Economic Area, the General Data Protection Regulation gives you the right of access to your personal data, the right to have it corrected or erased, the right to restrict or object to how we use it, the right to receive it in a portable form, and the right to withdraw consent at any time without affecting anything done before you withdrew it.

You also have the right to lodge a complaint with the data protection authority in the country where you live or work.

Your rights over your information

You can ask us what personal information we hold about you and ask for a copy of it. You can ask us to correct it if it is wrong, ask us to delete it, and object to us using it in a particular way. Where we rely on your permission, you can take that permission back at any time.

To make any of these requests, use the contact details at the end of this policy. We will not charge you for a request and we will not treat you differently for making one.

Some requests are limited by law. We may have to keep particular records to meet legal, accounting or security obligations, and where that applies to your request we will tell you which records and why.

If you are not happy with how we handle your request, you can complain to the data protection authority for your country.

Why we are allowed to use your information

For anything on this site that needs your permission, including non-essential cookies, our basis is the permission you give through the cookie banner, and you can take it back at any time without affecting anything we did before you did.

For the other information described above, our reasons are:

  • A contract with you: to run your account (including when you sign in with Google), deliver the services you bought, process orders, let Watchers work on the platform and pay them.
  • A legal obligation: keeping invoices, tax records and payout records.
  • Our legitimate interests: keeping the site and app secure, preventing fraud and abuse, checking alarms in the Tribunal, and improving our service. We weigh these against your privacy.
  • Your consent: newsletters and non-essential cookies. You can withdraw it at any time.

Keeping your information secure

We protect all personal information with the same measures described for Google user data above: encryption in transit and at rest, restricted access, protected secrets and signed requests between our systems. No website and no way of sending information over the internet is completely secure, so we cannot promise absolute security.

Links to other websites

This site may link to websites we do not run. Those websites have their own privacy policies and their own practices, and we are not responsible for their content or what they do with your information.

Changes to this policy

We may update this policy when this site changes, when what we do with information changes, or when the law changes. When we do, we will publish the new version on this page and update the date at the top. If a change means we need your permission for something new, we will ask you for it.

How to contact us

If you have a question about this policy, or you want to exercise any of the rights described above, you can reach us here:
