Privacy Policy

Last updated: 28 August 2026

This website is operated by Siddartha Bahri, sole proprietor, trading as Echelon Consulting, 729, Udyog Path, RK Developers & Infrastructures Pvt Ltd, Sector 22A, Chandigarh 160022, India ("we", "us"). This policy explains what personal data we collect, why, and what you can do about it. It is written to meet our obligations under the Digital Personal Data Protection Act, 2023.

Who to contact

Siddartha Bahri, trading as Echelon Consulting, acts as the Data Fiduciary for the data described here. For any question, request or grievance regarding your personal data, write to sid@sidbahri.com or call +91 70877 65555.

What we collect

When you contact us. Your name, email address, organisation if you provide one, your area of interest, and whatever you write in the message field.

When you take the DO Diagnostic. Your name and email address, your written responses to the assessment scenarios, and a cohort or partner code if you arrived through one. Diagnostic responses are free text you compose yourself; please do not include personal information about yourself or others that the assessment does not ask for.

When you use DO Communication Practice. See the dedicated "DO Communication Practice" section below, which describes what Practice collects and how it is processed separately from the Diagnostic.

When you enrol or express interest in a programme. Your name, email address, phone number, organisation if provided, the programme you selected, and any cohort, capability or coupon code carried in the link you followed.

When you pay. Payments are processed by PayU Payments Private Limited. We receive confirmation of the transaction and the details you supply for invoicing. We do not receive or store your card number, UPI PIN, CVV, or bank credentials.

Automatically. We use Google Analytics, which sets cookies and collects usage data including approximate location, device and browser type, and pages visited. You can opt out using Google's browser add-on or by blocking cookies in your browser.

Why we collect it

To respond to your enquiry; to score your Diagnostic and send you your report; to run DO Communication Practice as described below; to process your enrolment, take payment and deliver the programme you bought; to send you information about programmes you have asked about; to meet our tax and accounting obligations; and to understand how the site is used so we can improve it.

Consent, and withdrawing it

Where we rely on your consent, you give it by submitting the relevant form or by accepting the in-app Data & Privacy notice, and the notice at that point tells you what you are consenting to. You may withdraw consent at any time by writing to sid@sidbahri.com. Withdrawal does not affect processing already carried out, and it may mean we can no longer provide a service you have asked for.

Where your data is processed

DO Diagnostic responses are scored on our own hardware in India. They are not sent to any third-party AI service for scoring. This applies only to the Diagnostic; DO Communication Practice's use of third-party AI is described separately below and is not covered by this sentence.

Data is stored on Google Firebase in the asia-south2 region, in India. Some service providers we use may process data outside India: Resend (email delivery), Formspree (contact form handling), Google Analytics, and, for DO Communication Practice only, OpenAI (see below). Payment data is processed by PayU in India.

DO Communication Practice

This section describes DO Communication Practice specifically -- the self-serve capability-practice product accessed through its own signed-in app. It does not change or narrow anything said above about the separate DO Diagnostic, and nothing said about the Diagnostic elsewhere on this page should be read as describing Practice.

Data you provide. Your account and profile information (name and email from sign-in; role, industry, and similar practice-context fields you enter); the practice configuration and context you select for a session; your typed responses; and, where you choose text, audio or video, your audio or video responses.

How responses are processed.

Text. Your response text is analysed to generate communication and language feedback.

Audio. Audio is processed on our own infrastructure for transcription and paraverbal analysis (pace, filler words, pauses, pitch variation). The resulting transcript and other derived information are used for scoring, as described below.

Video. Video is processed on our own infrastructure for the audio track's transcription and for non-verbal signals (posture, gaze, hand-to-face contact). Raw video is not sent to any third-party AI service. Derived textual and contextual information used for evaluation may be sent to a third-party AI service, as described below.

Use of third-party AI services. DO Communication Practice uses third-party AI services for: (a) scoring your response against our communication rubric; (b) language and grammar analysis of your response; and (c) generating the practice scenario you respond to. The provider we use for this is OpenAI (see "Where your data is processed" above). This is different from the Diagnostic, which is not sent to any third-party AI service. For Practice, your account identifiers (user ID, email, name) are not deliberately included in these calls; your response text or transcript, and the scenario/context needed for evaluation, are sent where required to score your response and generate feedback. Original audio and video files are not sent to any third-party AI service at any point.

What we store. For Practice we store your profile information; your practice attempts; transcripts of audio/video responses; your scores; feedback generated for you; and derived communication, language, paraverbal and (for video) non-verbal measures; and records of what you are entitled to access. We keep this for as long as your account is active and for our legitimate operational needs (for example, tracking your progress over time); we do not currently run an automatic deletion after a fixed number of days. You can ask us to delete your Practice account and data by writing to sid@sidbahri.com, and we will act on that request as described in the app's Data & Privacy screen and under "Your rights" below.

Temporary media handling. An audio or video file you submit is processed temporarily by our systems (for transcription and the analysis above) and is not kept afterward as a stored recording. Temporary processing files are cleaned up once processing completes, and any temporary files left behind by an interrupted process are also cleared during routine maintenance checks. We do not describe our internal processing architecture further here; write to us if you have specific questions.

What we do not do with non-verbal signals. Where video is used, we describe physical signals such as posture, gaze and hand-to-face contact. We do not infer confidence, honesty, nervousness, credibility, competence or engagement from these or from your appearance, and Practice does not perform any such psychological analysis.

Age. DO Communication Practice requires you to confirm you are 18 or older before first use.

Who we share it with

We do not sell your personal data. We share it only with the service providers named above -- including, for DO Communication Practice, OpenAI, to the extent described above -- to the extent needed to run the service, and with tax or legal authorities where the law requires it.

How long we keep it

Enquiries: up to 24 months from your last contact with us. Diagnostic responses and reports: up to 24 months, after which they are deleted or anonymised. DO Communication Practice data: see "What we store" above -- kept while your account is active and for our legitimate operational needs; there is currently no fixed automatic deletion period, and you may ask us to delete it as described there. Enrolment and payment records: as long as tax and accounting law requires, currently eight years. You may ask us to delete your data sooner and we will do so unless we are required to keep it.

Your rights

Under the DPDP Act you may ask us for a summary of the personal data we hold about you and how we process it; ask us to correct anything inaccurate or incomplete; ask us to erase data we no longer need; and nominate another person to exercise these rights on your behalf if you die or become incapacitated.

Write to sid@sidbahri.com. We will respond within a reasonable period. If you are not satisfied with our response, you may complain to the Data Protection Board of India.

Children

Our services are intended for adults. We do not knowingly collect personal data from anyone under 18. If you believe a child has given us data, write to us and we will delete it.

Security

We use access controls, encrypted connections and restricted credentials to protect your data. No system is perfectly secure, and we cannot guarantee absolute security.

Changes

We may update this policy. The date at the top shows when it last changed. Material changes affecting how we use your data will be notified by email where we hold your address.
