Questions & answers
How Transfore works, what to expect during a migration, and how we handle your data — without storing your passwords or score history on our servers.
Common questions
How does Transfore work?
You connect both apps — your source (where scores live today) and your destination (where you want them copied). We show a preview of your rounds, you choose what to import, then we write those rounds to the destination using your authorized session.
This is a one-time migration, not background sync. When you finish (or your session expires), nothing keeps running.
How long does a migration take?
Most people finish in a few minutes once both apps are connected. Time depends on how many rounds you import and whether you unlock the full migration for hole-level stats.
Your browser session stays active for about 30 minutes so you can preview, pay if needed, and migrate without logging in again for every round.
Do I need to connect both apps before preview or migrate?
Yes. Preview and import need a live session to both the source and destination accounts. Connect the source first, then the destination on the next step — the wizard walks you through it in order.
Why do I need to connect The Grint before purchasing a license?
Each license is tied to one Grint account — that is the account we verify at checkout and activation. For 18Birdies → The Grint, Grint is your destination, so that rule matches where your history is landing. For The Grint → 18Birdies, the license still binds to your Grint account (the source you export from).
You still connect both apps in order before preview and migrate. Direction only changes which app is step 1 vs step 2.
Will I get logged out of 18Birdies or The Grint on my phone?
18Birdies — usually yes. 18Birdies allows only one active login at a time. When you connect here, that new session typically signs you out of the 18Birdies app on your phone. Sign back into the app after you finish migrating (or use the app first, then run Transfore when you are ready).
The Grint — usually no. In our experience, connecting through Transfore does not kick you off The Grint mobile app the same way. Your phone session often stays active.
Either way, we use your password only once to obtain session tokens, then discard it immediately. Those browser tokens are separate from your phone apps.
What's free vs. paid?
You can preview your full round list for free. The free tier lets you import 1 round per migration (summary scores). Unlocking with a license removes the round limit and includes hole-by-hole detail when available — putts, tee accuracy, and per-hole scores.
What if a round already exists in the destination?
By default we skip duplicates — same date, gross score, and 9 vs 18 holes — so you do not create twin scorecards. You can turn that off on the migrate screen if you intentionally want to retry.
Is Transfore affiliated with The Grint or 18Birdies?
No. Transfore is an independent tool. You authorize us to move your own data between apps you already use. We do not sell your information or run ongoing sync in the background.
How much does full migration cost?
$9.99 one-time unlocks your full history for import. The free tier lets you migrate 1 round with hole detail when available. Beta testers may receive a one-time Stripe promotion code from us.

Security & data storage
What we never store
- ✓Passwords are used once to start a login, then discarded. They are not written to disk, a database, or logs.
- ✓Your round history is not saved on our servers. We read it during preview/migrate and pass it to your destination in that session only.
What exists during a migration session
After you connect each app, we keep short-lived session tokens (the same kind your browser or phone would use) inside one encrypted cookie on your device. That lets us fetch rounds and write them to the other app while you complete the wizard.
Session lifetime
About 30 minutes, then the cookie expires.
Cookie protection
Encrypted, httpOnly, not readable by page scripts.
License key
Stored in the same session cookie until it expires.
Disconnect anytime
Clears tokens from your session immediately.
Your data stays yours
Transfore is built for personal, user-authorized export and import. We do not scrape public profiles, bypass paywalls, or retain a copy of your scorecards after the session ends.
