We respect your privacy and are committed to handling your information responsibly. This Privacy Policy explains what information we collect when you use RiceCaliper, how we use it, how we protect it, and the choices available to you.
By creating an account or using RiceCaliper, you acknowledge the practices described in this Privacy Policy.
We collect information that is necessary to provide and improve RiceCaliper.
Account information. When you create an account, we collect your name, mobile number, password, and one-time passwords (OTP) used for authentication. You may also choose to provide your email address, company or business name, business address, and GSTIN. Company, address, and GSTIN information may be used for generating invoices and maintaining appropriate business records.
Rice sample images and analysis data. When you use RiceCaliper to analyse a rice sample, the image you submit is uploaded to our servers for processing. Depending on the features available in your version of RiceCaliper, we may generate and store rice grain counts, whole and broken grain measurements, grain dimensions, chalky or discoloured grain information, other quality characteristics, analysis results and reports, sample or batch information you enter, and dates, times, remarks, or other information associated with an analysis. Your historical analyses and reports may remain available in your RiceCaliper account so that you can review them later.
Calibration sheet downloads. RiceCaliper's printed calibration sheet carries a unique identifier. When you download a calibration sheet, we record that identifier together with your account (or, if you are not signed in, an anonymous device identifier) and the date of download, so that a later analysis can be linked back to the specific printed sheet it was taken on. This is used for quality and troubleshooting purposes only — for example, to identify a specific printed sheet if it is damaged or defective — and is not used to determine who physically took a photograph, since a printed sheet may be shared, reused, or handed to someone else after it is downloaded.
Payment information. Payments made through RiceCaliper are processed by Razorpay. We do not store your complete card, bank account, UPI, or other payment credentials on our own servers. Payment information may be handled and, where supported, securely stored by the payment service provider according to its own policies and terms.
We may use the information we collect to:
RiceCaliper uses computer-vision and AI-based technology to analyse rice samples. To continuously improve the accuracy of our analysis, rice-sample images submitted to RiceCaliper may be retained and used to improve our analysis algorithms and models.
For example, if our system incorrectly identifies a rice grain, misses a grain, or identifies a fragment or other object as a grain, the relevant data may be used to improve the system and reduce similar errors in the future. This means that your submitted rice-sample images may contribute to improving RiceCaliper's technology over time.
We do not sell individual rice-sample images to third parties.
We understand that rice analysis results, sample information, quality measurements, and related business information may be commercially confidential. We do not sell or publicly disclose your individual analysis reports or business data.
Authorised RiceCaliper personnel may access account, analysis, or sample information when reasonably necessary to:
We take reasonable steps to limit such access to legitimate business purposes.
We may create and use aggregated, statistical, or anonymised information derived from the use of RiceCaliper, such as trends by rice variety, geographic or state-level trends, quality characteristics and trends, statistical analysis of rice samples, and general usage and product-performance trends. Such information is designed so that it does not identify a particular customer or individual.
We may use, publish, share, license, or commercially use aggregated and anonymised information for purposes including research, analytics, benchmarking, industry insights, product development, and other legitimate business purposes.
We do not sell your personal information or individual rice-sample images to third parties.
We may share information with trusted service providers when necessary to operate RiceCaliper, including for cloud hosting and infrastructure, payment processing, OTP and WhatsApp communications, analytics, and security and technical operations. For example, RiceCaliper uses Razorpay for payment processing, Twilio for WhatsApp communications, and Google Analytics for website and service analytics.
We may also disclose information where reasonably necessary to:
RiceCaliper uses third-party communication services to send OTPs and other service-related messages through WhatsApp. Your mobile number may therefore be shared with the relevant communication service provider for the purpose of delivering these messages. RiceCaliper does not use your mobile number to sell or distribute your personal information to unrelated third parties.
RiceCaliper's website and application may use cookies, session technologies, and similar technologies to keep you signed in, maintain your session, remember necessary settings, improve security, understand how users interact with the service, and improve website and product performance.
We use Google Analytics to understand website and product usage. Analytics information may include pages viewed, interactions, device or browser information, approximate geographic information, and other usage information.
You can control cookies through your browser settings. Disabling certain cookies may affect some RiceCaliper features.
We take reasonable technical and organisational measures to protect information against unauthorised access, alteration, disclosure, loss, or misuse. However, no internet-based service can guarantee absolute security. You are also responsible for keeping your RiceCaliper password confidential and for notifying us if you believe your account has been accessed without authorisation.
We retain information for as long as reasonably necessary to provide RiceCaliper, maintain your account and analysis history, improve our services, meet contractual obligations, resolve disputes, prevent fraud, and comply with applicable legal, tax, accounting, or regulatory requirements. Rice sample images and analysis data may be retained for product and model improvement purposes.
You may delete individual reports or other data where the relevant RiceCaliper feature allows you to do so. Certain information, including information required for legal, tax, accounting, payment, fraud-prevention, or regulatory purposes, may need to be retained even after you request deletion of your account.
You may request deletion of your RiceCaliper account and associated data by contacting us at [email protected].
When we receive a valid deletion request, we will take reasonable steps to delete the data associated with your account, subject to information that we are required or permitted to retain under applicable law or for legitimate legal, accounting, tax, security, or fraud-prevention purposes. For example, certain mobile-number, GST, invoice, and payment-related records may need to be retained for legal or accounting purposes.
Deletion of your account may mean that you can no longer access your previous reports or use certain RiceCaliper services associated with that account.
RiceCaliper is designed for business and professional users and is not intended for use by children. We do not knowingly collect personal information from children for the purpose of providing a child-oriented service. If you believe that a child has provided personal information to us without appropriate authorisation, please contact us at [email protected].
RiceCaliper relies on certain third-party services to operate and improve the platform. These providers may process information in accordance with their own privacy policies and terms. Our current service providers may include:
We encourage users to review the privacy policies of relevant third-party providers where appropriate.
We may update this Privacy Policy from time to time to reflect changes to RiceCaliper, our practices, technology, or applicable legal requirements. When we make material changes, we may provide appropriate notice through the RiceCaliper website, application, email, or other suitable communication channels. The "Last updated" date at the top of this Privacy Policy indicates when the policy was most recently revised.

Follow these two steps to get accurate measurements with RiceCaliper.
Print this sheet at 100% / Actual size. In your print settings, select "Actual Size" (or turn off "Fit to Page" / "Shrink to Fit").
Correct
100% / Actual size
Incorrect
Printed smaller (Fit to Page)
When you place your sample on the sheet, spread the grains in a single layer with space between them. Don't let them touch or overlap.
Correct
Grains are separate
Incorrect
Grains touching or overlapping
Photograph your sample on the calibration sheet. Get Length, Width, L/W Ratio, Broken %, and a shareable report.
First time?
±0.1 mm accuracy vs. manual measurement, validated across hundreds of samples
A vernier caliper measures a handful of grains, one at a time. RiceCaliper measures every grain in your sample against a printed calibration reference, then gives you a permanent, shareable report.
How it works
~30 seconds, no lab equipment needed02 Spread & scan
Spread the grains in a single layer on the sheet and take a photo. Any phone camera works.
03 Report
Every grain is automatically outlined and measured. Get a full report in seconds to save, compare, and share.
Every report includes all of the above. Save, compare, and share it.
Features
Grain measurements
Length, width, aspect ratio, and area for every grain in the sample, not just an average.
Broken-grain analysis
Automatic broken-grain detection against a reference whole-kernel length, with an adjustable cutoff.
Custom standards
Set your own quality spec per buyer or variety, and evaluate future samples against it. Not just a generic pass/fail.
Compare samples
Compare two or more reports side by side to see how a variety or supplier changes over time.
History & trends
Every saved sample stays in your account, so quality trends are visible across a season, not just one scan.
Share & export
Send a verified report link a buyer can open with no account. Or print it straight to PDF.
Who it's for
Millers
Verify your milling output meets your specs before it ships. Catch broken-grain or size issues before your buyer does.
Brokers & traders
Back up your quality claims with a verified report link that buyers can open and check themselves.
Procurement
Check an incoming lot against your own specs before accepting it. One photo replaces manual sample counting at the dock.
QC teams
Replace manual vernier-caliper measurements with consistent, repeatable measurements for every grain, plus a report you can save and file.
Basmati grades are measured against the full grain. Enter the variety above, or the length below.
Grains shorter than this % of a whole grain count as broken. 75% is standard.
Broken grains shorter than this % count as small broken. Must stay below the cutoff above.
