The public app no longer has this from 3.0.1. Korea Investment & Securities does not allow account linking in apps from non-financial companies, so it was removed. 3.0.1 deletes saved keys on first launch and keeps the accounts, holdings and quantities you already filled in. What follows describes 3.0.0.
From 3.0 · Korea Investment & Securities only · Reads balances only — it never places orders. Available on iPhone · iPad · Mac · Android.
Golgoru does not trade for you. Make the trades your adjustment plan suggests in the Korea Investment app. Afterwards, read the balances again in Golgoru and your accounts match the real numbers.
What you need
| What | Where |
|---|---|
| Start with Enter my assets | Settings > Data > Start with (you can't link in Sample mode) |
| App key · app secret | Issued to you on KIS Developers — Korea Investment issues one per account |
| First 8 digits of the account number | Account details in the Korea Investment app |
Linking
- Sign in to KIS Developers (Korea Investment's open API portal), apply for API access and get a live app key and app secret.
- In Golgoru open Settings > Brokerage connections > Korea Investment · Live.
- Enter the app key, app secret and the first 8 digits of the account number.
- Turn on "This key is mine, issued for an account in my own name" and save.
- Tap check the connection — it asks the Korea Investment server for an access token.
- Find and link accounts looks up every account opened with that key (brokerage · pension savings · IRP · retirement DC …). For each one, link it to an existing Golgoru account or add it as a new account — a new account is filled from the balances right away.
If you have several accounts, each has its own app key: use Add a key group for the others. Give each group a name you'll recognise (e.g. ISA · Pension).
You can also start from account editing — it links what it finds to that account and fills it in.
- iPhone · iPad · Mac: in ⋯ > Edit at the top right, long-press an account and choose Find and link an account at Korea Investment (Live)
- Android: in ⋯ > Edit at the top right, tap ⋯ next to the account and choose Find and link an account at KIS Live
Matching balances again
- Open an account on the Assets tab: the top shows the link and when it was last synced. Tap it to see what differs from the brokerage (quantities · average prices · cash) — nothing changes until you tap Apply.
- In account editing — on iPhone · iPad · Mac long-press the account and choose Import from linked Korea Investment (…) · Pension savings; on Android tap ⋯ and choose Import balances from the linked account.
- If you ran an adjustment plan in the Korea Investment app, open the plan in progress and use Finish round N from brokerage balances — instead of ticking orders off one by one, it uses what actually filled. The round is marked done only after you tap Apply (if the lookup fails or you just close it, the round stays open).
Keys and privacy
- The app key, app secret and account number are stored only on this device — in the Keychain on iPhone · iPad · Mac (Face ID or the device passcode to read), encrypted with the Android Keystore on Android.
- Balances are read directly from the device to Korea Investment. They never pass through a Golgoru server, and the developer never receives your keys, accounts or balances.
- The link itself doesn't store your account number — only which key and account type go with which Golgoru account.
- Links stay on this device. Keys live only on the device, so a link travelling to another device would look connected without a key there. To use it on another device, enter the key on that device.
- Don't enter someone else's app key. Handing over or borrowing an app key can count as lending an access medium, which Korea's Electronic Financial Transactions Act prohibits.
What it doesn't do
- Orders or reserved orders — Golgoru never trades for you.
- Brokerages other than Korea Investment, or paper-trading accounts.
- Linking in Sample mode.
