NumberNote ("we", "us") is operated by Buhle Sihlangu, a sole proprietor based in South Africa. This policy explains what personal information we collect, why, and how we protect it, in line with South Africa's Protection of Personal Information Act (POPIA) and, where applicable, the EU General Data Protection Regulation (GDPR).
Information we collect
- • Account information: name, email address, and authentication details (including information from Google Sign-In, if you use it).
- • Uploaded data: spreadsheets (CSV/Excel) or pasted data you submit for analysis.
- • Usage data: how you use NumberNote, including analyses run and credits consumed.
- • Payment information: handled entirely by our payment processor, Paystack. NumberNote does not store your card details.
How we use your information
- • To provide and operate the service, including running your analyses.
- • To communicate with you about your account, billing, and support.
- • To improve NumberNote's features and reliability.
- • To send Claude (Anthropic's AI model) a compact summary and calculated context derived from your data, in order to generate insights. We do not send your full raw spreadsheet to Claude automatically.
Data retention
- • Uploaded spreadsheets and analysis history are retained while your account is active.
- • If you delete your account, your uploaded data is permanently deleted within 30 days.
- • You may request earlier deletion at any time by contacting numbernote.support@gmail.com.
Data sharing
We do not sell your personal information. We share data only with:
- • Paystack, to process payments.
- • Anthropic (Claude API), to generate analysis insights from a compact, calculated summary of your data.
- • Service providers necessary to operate NumberNote (e.g. hosting, database providers), bound by confidentiality obligations.
Your rights
Under POPIA (and GDPR, where applicable), you have the right to:
- • Access the personal information we hold about you.
- • Request correction of inaccurate information.
- • Request deletion of your data.
- • Object to certain processing of your data.
To exercise these rights, contact numbernote.support@gmail.com.
Security
We take reasonable technical and organizational measures to protect your data, including encrypted connections (HTTPS) and access controls on our production database. No system is perfectly secure, and we cannot guarantee absolute security.

We may update this policy from time to time. Material changes will be communicated via email or a notice on NumberNote.
