We do not sell user data

We do not use uploaded files or prompts to intentionally build public datasets or sell user data.

Stripe handles card payments

AskNagi does not directly store full card details; payment data is handled by Stripe.

Upload files responsibly

Users should only upload spreadsheets they are authorised to process.

01

Data we collect

We may collect account data such as email, display name when available and authentication provider; project data such as project titles, prompts, chat messages and workbook instructions; uploaded files and spreadsheet metadata; generated outputs such as Excel files, summaries, dashboards, charts and reports; usage data such as AI actions, downloads, plan limits and timestamps; billing-related records such as subscription status, Stripe customer ID, subscription ID and plan; and technical data such as logs, errors and browser or device information where applicable.

02

How we use data

We use data to provide AskNagi, create, edit, analyse and export Excel files, maintain project history, manage accounts and subscriptions, enforce Free and Pro limits, improve reliability, security and performance, detect abuse, fraud or technical issues, and provide support when requested.

03

Uploaded Excel files

Uploaded files may contain business, financial or personal data. Users should only upload files they are authorised to process. AskNagi processes uploaded files to provide requested features, and generated outputs may be stored so users can continue working. Users should avoid uploading highly sensitive data unless it is necessary.

04

AI processing

Prompts, workbook content and metadata may be processed by AI systems to generate edits, explanations, formulas, summaries, dashboards or downloadable files. Depending on the configured infrastructure, third-party AI providers may process content only for service functionality. We do not use uploaded files or prompts to intentionally build public datasets or sell user data.

05

Third-party services

AskNagi may use trusted third-party services including Supabase for authentication, database and storage; Vercel for frontend hosting; Railway for backend hosting and processing; Stripe for payments and subscriptions; Google services for Google login or Google Sheets export/opening where used; Cloudflare Turnstile for bot and abuse protection on sign-in (see Cloudflare's Turnstile Privacy Notice at https://www.cloudflare.com/turnstileprivacypolicy/); and AI providers for processing prompts and workbook content.

06

Payments

Payments are handled by Stripe. AskNagi does not directly store full card details. We may store subscription status, customer IDs, subscription IDs and plan information in our database. Stripe may process payment, billing and tax-related data under its own terms and privacy policy.

07

Data retention

Projects, prompts, uploaded file references and generated outputs may be stored while the account is active. Some logs or usage events may be retained for security, billing and abuse prevention. Users may request deletion of account data, while some billing or legal records may need to be retained where required by law.

08

User rights

Where applicable, users may request access to their data, correction, deletion, export or portability, restriction or objection, and withdrawal of consent where processing is based on consent. Users can contact AskNagi to exercise these rights.

09

Security

We use authenticated accounts, access controls, secure third-party infrastructure and restricted access where possible. No method of transmission or storage is 100% secure, and users should protect their account credentials.

10

Cookies and local storage

AskNagi may use essential cookies or local storage for login sessions, language, theme and product functionality. If analytics or marketing cookies are added later, this policy should be updated and consent handled where required.

11

International data transfers

Data may be processed by infrastructure providers located in different countries. Where required, appropriate safeguards should be used.

12

Children

AskNagi is not intended for children under the minimum legal age required to use online services in their country.

13

Changes to this policy

We may update this policy as the product evolves. Material changes should be communicated where appropriate.
