Privacy Policy

Who we are

Dendera is operated by Seismic LLC, 138 Delta Ave, Paonia, CO 81428, United States. We decide how the personal information described here is used, and we are responsible for it. You can reach us at hello@dendera.ai.

Information we collect

We collect your email address and, if you add it, your name. For your chart we store your birth date, your birth time or a note that it is unknown, and your birthplace with its coordinates and timezone. We also store the charts you save, your conversations with Dendera, your notification settings, and your subscription status.

When you open Today from the link in a forecast email, we record which edition you followed and its date, with your account. When you open the sources under one of Dendera’s answers in your conversations, we record which answer, with your account.

We also record how the service is used, such as the features you open and the pages you view, and technical information such as your device type, browser, approximate country, and error reports.

If you add a chart for someone else, such as a partner, a relative, or a child, we store the birth data you enter for them in your account. We use it as this policy describes. Add another adult’s details only with their permission, and a child’s only if you are their parent or guardian.

How we use it and our legal basis

We use this information to run Dendera: to calculate charts, generate the readings and answers you ask for, sign you in, manage subscriptions, send the email described below, prevent abuse, fix errors, and keep the service reliable. We do not sell your personal information, and we do not share it for cross-context behavioral advertising.

If you are in the UK or the European Economic Area, these are our legal bases. We provide your account, readings, chat, and paid features because you asked for them, under our contract with you. We rely on legitimate interests to secure the service, prevent abuse, fix errors, and understand how Dendera is used, weighed against your rights. We rely on your consent for optional email you choose to receive. We keep some records because tax and accounting law requires them.

Email and tracking

Brief emails list computed transit facts for your chart. If you have a paid plan, the weekly, monthly, and yearly briefs are on by default, and the daily brief is sent only if you turn it on. A free account can choose one brief each Sunday. Transit alerts, and briefs that include a partner or family members, are sent only if you turn them on.

Product-update email is on unless you turn it off. Every one of these emails has an unsubscribe link, including one-click unsubscribe, and you can change them in Settings.

Our emails contain no tracking images, and we do not record whether you open them.

Service providers

We share information with the providers that run parts of Dendera for us, and only what each one needs. Supabase stores our database and runs sign-in, in the United States. Vercel hosts the site and measures its page views and page speed. Sentry receives error reports; session replay is off, and reports are set up without default personal identifiers or request bodies. Resend delivers our email. Stripe processes web payments. Apple processes App Store purchases under Apple’s own privacy policy. Google and Apple run their sign-in options if you use them. Cloudflare Turnstile runs a bot check when you sign up or sign in with email. Geoapify turns a typed birthplace into coordinates, and OpenStreetMap’s Nominatim service does the same when Geoapify cannot answer.

Optional model polish is coming; replies currently use the engine’s wording. Before any model polish, we ask for your explicit consent. For a birthplace lookup, we send only the typed place name and a label that identifies Dendera, not your account. These providers process information for us under their own terms.

With your consent, Google Gemini receives your question, the last few turns, the chosen route, this turn’s engine statement texts and ids, abstention reasons and your language preference. It writes a conversational frame and restates only the supplied statements. For a full plain-language reading, it may also receive checked examples of how to phrase the selected statements. When you choose Haiku, Gemini also receives the established statement texts and ids to write an original companion poem. Personal details detected locally are withheld. No chart birth data, coordinates, reader name, email or account metadata is included.

With the same consent, TypeSafe’s Jev receives your question, the last few turns, the last selected route and the chart’s object names to choose a tool and closed-set arguments. It also receives proposed restatements with their cited statement texts and ids, and frame sentences with your question and this turn’s tool results, to check wording. When you enable philosophical reflection, Jev also receives the established statement texts and public-domain candidate passages to check relevance. For Haiku, it checks the poem against the established statements. We retain the selected source references and relevance decisions with the reading. Personal details detected locally are withheld. No chart birth data, coordinates, reader name, email or account metadata is included. You can withdraw consent for both services in chat settings.

If you agree to library search, TypeSafe’s Jev receives your library question, including a general question you ask Dendera, with the chapter openings and passages of the public-domain books it searches, to choose a book, a chapter and a passage. A question with a date, a time, coordinates, a link, a phone number, a full name, or a name with “my” is not sent, and no chart birth data, reader name, email or account metadata is included. You can withdraw that consent on the library page.

If you connect another application to your Dendera account, it can read your saved charts until you disconnect it on the connected assistants page.

International transfers

Our database is in the United States. If you use Dendera from outside the United States, your information is processed there, and it may also be processed in other countries where the providers above operate. Where UK or EU law requires a safeguard for that transfer, we use the Standard Contractual Clauses incorporated in our providers’ data processing terms.

Cookies and on-device storage

We use cookies to keep you signed in. We do not use advertising cookies. Your browser also stores your theme.

Our own page-view analytics do not set cookies. They keep a random visitor code in your browser’s local storage and a session code that lasts only for the visit. They record the pages you view and the campaign details in the link you followed. We do not store your IP address with these records; we keep only an approximate country and the general type of your device, browser, and operating system. This page-view tracking switches off when your browser sends a Do Not Track or Global Privacy Control signal. Vercel’s page-view and page-speed tools also run on the website.

Retention and security

We keep your account, charts, conversations, and settings until you delete them or your account is deleted. Deleting your account removes them from our live database. Copies in backups expire within 30 days.

Page-view records are deleted after 400 days. Product usage records are kept while your account exists. When you delete your account, the usage and page-view records we keep are no longer linked to it. Security and error logs are kept for up to 90 days. Our email provider, Resend, keeps its copies for 30 days, and our error-monitoring provider, Sentry, keeps its copies for up to 90 days.

We keep subscription and transaction records where tax or accounting law requires. App Store subscription records we keep after you delete your account are no longer linked to it. Stripe and Apple keep their own payment records. We use reasonable safeguards, but no internet service can guarantee absolute security.

Your choices and rights

To delete your account, email hello@dendera.ai from the address on your account. Deletion removes your account and the content we store for it, as the retention section describes. Providers that already received a copy, such as our email, payment, and error-monitoring providers, may keep it for their own periods.

Deleting your account cancels a web subscription billed through Stripe, so it will not renew. It does not cancel an App Store subscription; cancel that in your Apple Account settings.

If you are in the UK or the European Economic Area, you can ask to see, correct, or delete your information, to restrict or object to how we use it, and to receive a copy of it. There is no self-service download yet, so email us and we will send you a copy. You can also complain to your data protection authority.

If you live in California, you have the right to know what we collect and to ask us to correct or delete it. We collect identifiers (your email, your name if given, and your account id), commercial information (your subscription status), internet activity (usage, page views, and campaign details), approximate location (your country), and the birth data and content described above. We use them only for the purposes in this policy. We do not sell personal information or share it for cross-context behavioral advertising. You can appeal if we refuse a request, and we will not treat you differently for making one.

To make any of these requests, email hello@dendera.ai from the address on your account. We may need to confirm that the request comes from you.

Age

You must be at least 16 years old to create an account. We do not knowingly let a child open an account. A parent or guardian may keep a child’s chart in their own account. If you believe a child has opened an account, email hello@dendera.ai and we will delete it.

Sensitive information

Birth details, other people’s charts, and conversations can be personal. We use them only to produce the astrological interpretation you ask for and to run your account. We do not use them to build a profile of your health, mental health, or finances, and a reading is not a health record. Please do not submit medical or clinical information. You can delete a conversation, and you can ask us to delete your account.

If there is a breach

If a breach of personal information happens that the law requires us to report, we will tell the people affected, and the regulators the law names, within the time the law sets.

Changes

We will post any change to this policy here and update the effective date. If a change is material, we will email the address on your account before it takes effect where the law requires notice.
