Privacy policy

Who operates Vynko

Vynko (com.itoolverse.vynko) is developed and operated by iToolVerse, an individual developer. This policy covers the Vynko Android app and this website, vynko.itoolverse.com. For any privacy question, write to vynko.support@itoolverse.com.

What we collect

Account data. When you sign up with email and password, we store that through Firebase Authentication. If you sign in with Google, we receive your basic Google account profile — name, email, and photo.

Profile data. Your display name, and a profile photo — either your Google photo or a custom image you upload (up to 50MB), stored in Firebase Cloud Storage.

Financial ledger data you enter. Books, transactions (amount, date, category/subcategory, tags, payment mode, currency, and any free-text notes you add), goals, and budgets. This is manual entry only — Vynko never connects to a real bank account, card, or UPI provider.

Sharing data. If you share a Book, its co-members see your display name, your photo, and any nickname the Book owner has set for you.

Push notification token. A device-level token used only to deliver alerts such as "a member added a transaction" to other Book members.

Automatically collected technical data. Crash reports and stack traces (Crashlytics), app performance traces such as startup time, screen render, and network timing (Performance Monitoring), and usage/session analytics (Firebase Analytics/GA4). These all include device model, OS version, and app version — they describe the app's behavior, not your finances.

Local-only data. App settings and export-cooldown timestamps stay on your device and never leave it.

What we never collect

Vynko has no advertising SDKs and does no ad tracking — we don't sell or share your data with advertisers. We don't request precise or background location. This website sets no cookies and runs no third-party trackers or analytics.

Where your data is processed and stored

Your data is processed and stored on Google Firebase / Google Cloud, primarily in the asia-south1 (Mumbai) region, for the database, file storage, and server functions. Some of Google's own infrastructure — Analytics, Crashlytics, and Play services — may process technical data outside that region as part of Google's global infrastructure; this is standard for services built on Google's platform.

The following Google LLC services act as sub-processors on our behalf: Firebase Authentication, Cloud Firestore, Cloud Storage, Cloud Functions, Crashlytics, Performance Monitoring, Google Analytics for Firebase, Firebase Cloud Messaging, Firebase Remote Config, and Google Play services (In-App Update, In-App Review).

Retention and deletion

Deleting a Book (owner-only, in-app) deletes its transactions, categories, tags, and everything else stored in it. There is currently no in-app "delete my account" flow — full account deletion is handled manually by our support team on request. See how to delete your account for the exact steps.

Your rights

Access and export. The in-app Export feature lets you download your own data.

Correction. Edit any entry directly in the app.

Deletion. Delete a Book in-app at any time; request full account deletion via vynko.support@itoolverse.com.

Depending on where you live, you may also have rights to rectification, erasure, restriction of processing, data portability, and objection to processing, in line with GDPR- and CCPA-style protections. Contact us to exercise any of these rights.

Security

Data is encrypted in transit (HTTPS/TLS) and at rest using Firebase's default encryption. Cloud Firestore security rules restrict a Book's data to that Book's own members only.

Children

Vynko is not directed at children under 13, and we don't knowingly collect data from them. If you believe a child has created an account, contact us and we'll delete it.

Changes to this policy

When this policy changes, we post the new version here with an updated "last updated" date. If a change materially affects how your data is handled, we flag it in the app before it takes effect.

Contact and governing law

For any privacy question or request, write to vynko.support@itoolverse.com. This policy is governed by the laws of India, and the courts at Kolkata, West Bengal have exclusive jurisdiction over any dispute arising from it.
