Connect Google Drive

PratikYedek uses Google's app-folder scope (drive.appdata). We can only read and write files we created — your photos, documents, and other Drive files are invisible to us.

Prerequisites

• A personal or SME plan (tax-advisor plan is restricted)
• A Google account with at least 1 GB free
• Browser available for OAuth consent

Step 1 — Open Storage settings

1. Sign in to https://app.pratikyedek.com (or open the desktop/mobile app)
2. Navigate to Settings → Storage
3. Click Connect Google Drive

Step 2 — OAuth consent

A new browser tab opens with Google's consent screen:

• App: PratikYedek Yazılım (verified)
• Permission requested: "See, edit, create, and delete its own configuration data in your Google Drive" (this is the drive.appdata scope)

Approve to continue.

Step 3 — KVKK § 9 consent

Because Google Drive may store data outside Turkey:

• A consent modal lists target regions (US/EU multi-region)
• You explicitly accept the cross-border transfer (KVKK § 9)
• The consent is logged with timestamp + IP (KVKK § 12 evidence)

Step 4 — Connection test

The Test button:

1. Writes a 1 KB encrypted probe file
2. Reads it back
3. Deletes it
4. Confirms green checkmark in the UI

Step 5 — First BYOS snapshot

The next snapshot will:

• Encrypt files locally (AES-256-GCM)
• Upload encrypted chunks to your Drive's appDataFolder
• Store only metadata (chunk hashes, sizes) on PratikYedek servers

Token refresh

OAuth refresh tokens rotate every 6 months automatically. If a snapshot fails due to token expiry, you'll see a banner: "Reconnect Google Drive". One click reauthorizes; no data is lost.

Disconnect

Settings → Storage → Disconnect revokes the OAuth token. Existing chunks remain in your Drive (you can delete them manually from appDataFolder).

Troubleshooting

• "403 storageQuotaExceeded" — your Drive is full; upgrade Google One or free space
• "401 invalid_grant" — token revoked from Google account security; reconnect
• Slow uploads — Google rate-limits app-folder writes to ~5 req/sec; large snapshots use chunking + retry
