Cookie Policy
ThaiWealth AI · Effective 5 September 2026
What this page covers
A cookie is a small piece of text a site asks your browser to keep, so the next page you open knows something the last one did. We use them for two things only: to run the service you asked for, and, if you agree, to count how the app is used. This page lists every one of them and lets you change your mind.
We run no advertising cookies, and we do not sell or share what these cookies store with anyone for advertising. There is no third-party ad network on this site, no tracking pixel, and no cross-site profile of you.
Your choices
Necessary cookies are always on. Everything else stays off until you say otherwise, and you can change this whenever you like.
You have not made a choice yet. Until you do, only the cookies the site cannot run without are used.
Strictly necessary
Signing in, session security, your language, and the record of the choice you make here. These cannot be turned off, because without them the site cannot do the thing you came here for.
Always on
Counts of which screens and features get used, and masked recordings of how you move through the app, so we know what to fix first. It never includes your transactions, your statements, or anything you type into the app.
Your choice is stored in your browser for 180 days, after which we ask again. Clearing your browser's cookies clears it too, and the notice will come back.
Every cookie we use
Names ending in an asterisk are a family of cookies sharing a prefix; the full name includes an identifier that changes per project or per session.
Strictly necessary
These run without asking, because the service you asked for cannot work without them. None of them tracks you across other sites.
| Cookie | Set by | What it does | Stored for |
|---|---|---|---|
| sb-*, tw-auth-* | ThaiWealth AI | Keeps you signed in, and returns you to the page you were heading for after you sign in. Without it every page would ask you to sign in again. | Up to 400 days, or until you sign out |
| tw-cookie-consent | ThaiWealth AI | Remembers the choice you made about cookies, so we stop asking. | 180 days |
| NEXT_LOCALE | ThaiWealth AI | Remembers whether you are reading the site in Thai or English. | 1 year |
| tw-referral-code | ThaiWealth AI | Set only if you arrive through a referral link, so the referral you followed is applied when you create your account. It holds a referral code, not a profile, and is never used for advertising. | 30 days |
| tw-line-oauth-state | ThaiWealth AI | A one-time security check while you connect your LINE account, so nobody else can complete that connection in your name. Set only if you start that step. | Minutes, until the connection finishes |
| cf_*, __cf* | Cloudflare | Runs the automated bot check that protects the sign-in and sign-up forms from abuse. Set by our security provider on the pages where that check is switched on. | From 30 minutes to a year, depending on the check |
Product analytics (optional)
These run only if you allow them, and stop the moment you withdraw.
| Cookie | Set by | What it does | Stored for |
|---|---|---|---|
| ph_* | PostHog | Counts screens and features used, so we can tell what to improve, and may record how you move through the app with all text, typed values and images hidden. Set only after you allow analytics, and never records your transactions, your statements, or anything you type. | Up to 1 year |
| tw-first-touch | ThaiWealth AI | Remembers which campaign or website you first arrived from: the campaign name and the other site's address, never the page you were reading there. We attach it to your account when you sign up so we can tell which of our ads and posts bring people in. Set only after you allow analytics, and deleted if you refuse. | 30 days |
Similar storage on your device
A few things are kept in your browser's local storage rather than in a cookie: whether you chose the light or dark theme, small display preferences such as whether the sidebar is open and which calendar you read dates in, and which notices you have already dismissed. If you allow analytics, the analytics provider also keeps its own identifier there, along with a record of the answer you gave so it can honour it. All of this stays on your device, is never sent to us, has no expiry date, and is removed when you clear the site's data.
Controlling cookies in your browser
Every major browser lets you see the cookies a site has stored, delete them, and block new ones. Blocking the strictly necessary ones will stop signing in from working; blocking the rest costs you nothing here. Deleting our cookies also deletes the record of your choice, so the notice will reappear.
Changes to this policy
If we add a cookie, or change what an existing one does, we update this page and change the effective date above with it. Where a change means the choice you made no longer covers what we do, we ask you again rather than assume your old answer still stands.
Questions
How we handle personal data more generally is set out in our Privacy Policy, and how long we keep each kind of record is in the Data Retention Policy. If anything here is unclear, the privacy contact address in the Privacy Policy reaches us.
