KnowStock

Privacy Policy

Effective date: 9 October 2026

KnowStock is a service operated by Asquarete (“we”, “us”). KnowStock provides inventory, billing software for retail shops, delivered through the KnowStock Android app and the KnowStock web dashboard (together, the “Service”). This policy explains what data we collect, why, and what choices you have. It applies to shop owners and staff who use KnowStock (“you”, the “merchant”) and, where relevant, to the merchant's own customers whose records a merchant stores inside KnowStock.

1. Data we collect

Account & business data

When you register, we collect your business name, owner/staff name, email address and phone number, and create a tenant record isolated from every other business on KnowStock. This is used for authentication (JWT-based sign-in), account recovery, staff role management (owner/manager/staff), and product support.

Trial mode (before you create an account)

You can use KnowStock's camera scanning and billing without signing up. In this mode, your shop, product and sale data is stored only on your device (locally, in the app's offline database) and is never sent to our servers. If you later create an account (“claim” your trial), that local data is uploaded to your new tenant at that point — and only then.

Merchant business data (your shop's records)

Once you have an account, KnowStock stores the business records you create in the course of running your shop: products and stock counts, purchase orders and suppliers, sales and GST invoices, and your own customers' records — name, phone number, purchase/khata (udhaar) history, and, for optical shops that choose to use this feature, prescription details (SPH/CYL/AXIS/ADD, PD). Product photos you attach are stored as image links against the product record.

For this category of data, the shop is the data fiduciary (data controller): it is your customers' data, you decide what to collect and for how long, and you are responsible for having a lawful basis to store it (for example, your customer's consent to keep their prescription on file). KnowStock processes it only on your instructions, to provide the Service to you. We do not use your customers' data for our own marketing and do not sell it.

Shop customers' data

If you are a customer of a shop that uses KnowStock, that shop decides what is recorded about you and why, and is responsible for it as the data fiduciary / controller. KnowStock acts only as the shop's processor and handles that data solely on the shop's instructions. To access, correct or erase your records, ask the shop first; we will help the shop act on your request.

Anonymous product-usage telemetry

To understand how the trial-to-paid funnel is working, the app sends a small number of anonymous usage events (for example: app opened, trial started, first scan completed, first sale made, trial claimed) to our server. Each event carries a random, per-install device ID generated on your device (not tied to your name or phone number) and, if you already have an account, your tenant ID. We do not log or store your IP address against these events — it is used only transiently to rate-limit the endpoint against abuse, then discarded.

Payments

Paid plan checkout is handled by a third-party payment gateway (currently Razorpay). Card, UPI and net-banking details are entered directly into Razorpay's checkout and are never seen, transmitted through, or stored by KnowStock. We store only the outcome of a payment (plan, amount, status, Razorpay's transaction reference) so we can grant and reconcile your subscription.

Device permissions

  • Camera— used to scan barcodes for stock counts and billing. Scanning happens entirely on your device (on-device barcode decoding); no camera image or video is uploaded to our servers or stored by us.
  • Bluetooth— used only to connect to a barcode- label printer or hardware barcode scanner you choose to pair, if you own one. We do not use Bluetooth for location tracking or advertising, and Android's Bluetooth-scan permission is requested with the “neverForLocation” flag.

2. Why we use this data

  • To provide and operate the Service (billing, inventory, sync, reporting).
  • To authenticate you and keep your business's data isolated from other tenants.
  • To process payments and manage your subscription.
  • To provide customer support when you contact us.
  • To understand product usage in aggregate and improve the Service (anonymous telemetry).
  • To meet our legal obligations, including tax and accounting record-keeping.

3. Sharing

We do not sell your data or your customers' data. We share data only with:

  • Razorpay, to process payments you initiate.
  • Infrastructure providers that host our servers and database, strictly to operate the Service, under contracts that restrict them from using your data for any other purpose.
  • Law enforcement or regulators, only where legally required.

Exports you generate yourself — Tally CSV, GSTR-1 filing data, WhatsApp receipt shares — are user-initiated file downloads or native share-sheet actions. They are not automatic transfers to a third party by KnowStock.

4. Data location & retention

Your data is stored on servers operated by our infrastructure provider. We retain account and business data for as long as your account is active, and for a reasonable period afterward to meet accounting and tax record-keeping obligations under the law that applies to your business (for example, up to 8 years for financial records such as invoices in India). Anonymous telemetry events are retained only as long as needed for product analytics and may be aggregated or deleted thereafter.

5. Your choices & deletion requests

You can review and edit most of your account and business data directly inside the app or web dashboard. To request deletion of your account and associated data, use the account deletion request page (also reachable from Settings in the app), or email admin@asquaretech.co.in from your registered email address. To delete a specific customer record, email us the same way. We aim to complete requests within 30 days, and any copies in backups are removed within 90 days. We keep only records we are legally required to retain (for example, tax invoices).

6. Your rights

Under India's Digital Personal Data Protection Act, 2023 and, where it applies to you, the EU/UK GDPR, you have the right to:

  • access the personal data we hold about you;
  • have inaccurate or incomplete data corrected;
  • have your data erased (see the deletion requests above);
  • withdraw consent you have given, at any time, without affecting earlier processing;
  • seek redressal of a grievance, as described below.

To exercise any of these rights, or to raise a grievance, write to our Grievance Officer at admin@asquaretech.co.in. We will respond within 30 days. If you are not satisfied with our response you may also approach the Data Protection Board of India or your local data protection authority.

7. Children's privacy

KnowStock is a business tool for shop owners and staff and is not directed at children. We do not knowingly collect personal data from anyone under 18. If you believe a child has provided us with personal data, contact us and we will delete it.

8. Security

We use industry-standard measures to protect your data, including encrypted connections (HTTPS), JWT-based authentication with short-lived access tokens, and tenant-level data isolation. No method of transmission or storage is 100% secure, and we cannot guarantee absolute security.

9. Changes to this policy

We may update this policy as the Service changes. We will update the effective date above when we do, and for material changes we will make reasonable efforts to notify you in-app or by email.

10. Contact & grievance officer

For privacy questions, data access, correction or deletion requests, or complaints, contact us at admin@asquaretech.co.in. In accordance with the Information Technology Act, 2000 and the Information Technology (Reasonable Security Practices and Procedures and Sensitive Personal Data or Information) Rules, 2011, the Grievance Officer for KnowStock can be reached at the same address: admin@asquaretech.co.in. We aim to acknowledge grievances within 48 hours and resolve them within 30 days.
