Cinemistry
Privacy Policy
Last updated: 27 August 2026
Cinemistry (“we”, “us”) lets you create a short personalized greeting video and share it with a link. This policy explains what information we collect when you use cinemistry.com, why, and the choices you have.
What we collect
- Account details. Sign-in is handled by Auth0. When you sign in with email and password or with Google, we receive and store your email address, display name, and a unique account identifier. We never see or store your password or your Google credentials.
- Greeting content. The names you type (yours and the recipient’s) and the relation you pick. These appear in the rendered video and on its share page.
- Generated videos. The video files we render for you, plus a thumbnail.
- Technical data. Standard server logs (IP address, browser type, timestamps, pages requested) used to keep the service running and prevent abuse.
- Usage analytics. We use Mixpanel to understand how the site is used: which pages are visited and in what order, how long a page is read, which buttons are pressed, and where people stop part-way through making a video. This includes your browser and device type and an approximate location derived from your IP address. The names you type are never sent, nor is the web address of any greeting’s share page. If you are signed in, this activity is linked to your account by an internal identifier only — never by your email address or your name. We do not run advertising trackers, and we do not record your screen or what you type.
How we use it
- To render your greeting and show it on its share page.
- To let you sign in and find the greetings you have made.
- To apply fair-use limits (for example, a daily cap on renders per account).
- To secure the service, debug problems, and prevent misuse.
- To see which parts of the site people actually use, and where the process is confusing or broken, so we can fix it.
We do not sell your data and we do not use it for advertising.
Share pages are public
Every finished greeting gets a share page at cinemistry.com/g/<code>. Anyone who has the link can watch the video and see the names in it, and messaging apps such as WhatsApp may show a preview. Links are unguessable but not secret — only share them with people you want to see the greeting. Your email address is never shown on a share page.
Who we share data with
- Auth0 (Okta) — authentication. Auth0’s own privacy policy applies to the sign-in step.
- Google — only if you choose “Continue with Google”. We request just your basic profile and email; we do not access anything else in your Google account.
- Amazon Web Services — hosting and file storage (Mumbai region, India).
- Mixpanel — product analytics (servers in the United States). Receives the usage data described above: pages, clicks, timings, browser and device, and an internal account identifier. It never receives the names in your greeting, your email address, or your share links.
- Google Cloud Text-to-Speech — receives the two names you enter (and nothing else) to generate the spoken greeting in the video.
We share data with these providers only to operate the service, and with no one else.
Retention and deletion
Greetings and their videos stay available so your share links keep working. You can ask us to delete a specific greeting or your whole account at any time by emailing rajeev.sarathe@cinemistry.com from the address you signed up with. We will remove the videos, share pages, and account record within a reasonable time. Server logs are kept for a short period and then discarded.
Your rights
You can ask us what personal data we hold about you, ask us to correct it, or ask us to delete it. Write to rajeev.sarathe@cinemistry.com. We handle requests in line with India’s Digital Personal Data Protection Act, 2023 and other applicable law.
Children
Cinemistry is not directed at children under 13, and you must be old enough to hold your own Google or email account to sign in.
Cookies and local storage
We use one session cookie so you stay signed in, and Auth0 sets its own cookies during sign-in. Our analytics stores a random identifier in your browser’s local storage so that repeat visits can be recognised as the same device; it is first-party, holds nothing about you personally, and clearing your browser’s site data removes it. There are no advertising cookies and we share nothing with ad networks. If your browser sends a “Do Not Track” signal, we do not collect analytics at all.
Changes
If we change this policy we will update the date at the top of this page. Material changes will be called out on the site.
