We may collect the following information, only as necessary to provide
the service.

Email address (for registration, login,
verification codes, and security notices)
-
Login method and identifiers (e.g., Google
sign-in identifier)

3. How We Use Information
We use information only for:
-
Providing and maintaining core features (records,
stats, sync)
-
Authentication and account security (e.g., one-time
login/registration codes)
-
Abuse prevention and system security (e.g., rate
limiting, diagnostics)
- Legal compliance
About verification emails
-
We send one-time codes only to the email address
you provide for your own registration/login.
-
These are transactional/security emails, not
marketing bulk emails.
-
You may also choose third-party login (e.g., Google) to reduce
code usage.
4. Third Parties & Sharing
We do not sell your personal information. We use a limited set of
service providers to operate the App and deliver essential features.
-
Google Sign-In
- Used for third-party authentication and login.
-
We may process basic identifiers needed to complete sign-in
(e.g., an account identifier).
-
Third-party email delivery services
-
Used to send one-time verification codes and
security notice emails.
-
These emails are transactional/security emails,
not marketing bulk emails.
Data minimization
We share only the minimum information necessary to provide the
service. For example, to deliver a verification email via our email service provider,
we submit the
recipient email address and the
message content for delivery.
5. Storage, Retention & Security
We take reasonable measures to protect your information and retain it
only as long as necessary to provide the service and maintain
security.
-
Storage
-

reasonable period.
