Privacy notice
This notice states what Tideglyph holds about you, why it holds it, who receives it and what you may ask us to do. It gives the notice that section 18 of the Protection of Personal Information Act 4 of 2013 (POPIA) requires.
The responsible party
OmniStrata (Pty) Ltd is the responsible party for your personal information. Our Information Officer answers each request under this notice. Write to the support address.
What we hold and why
We hold only what Tideglyph needs to make your reading, keep your record and take a payment. Section 11(1)(b) of POPIA is the lawful ground: we need the record to give you the service you asked for.
| What we hold | Why |
|---|---|
| Email address and a hash of your password | To sign you in, to send the daily letter, and to confirm a cancelled plan. We never store the password itself. |
| Birth date, birth time, birth place and timezone | To calculate your birth chart and the daily transits |
| Each daily reading | To show today's reading and your history |
| Your mood and your journal notes | To keep your private record |
| Your plan, its status and its end date | To decide what you may open |
| Each payment record, and the Paystack card authorisation code | To confirm a payment. We never see or store the card number. |
| The daily letter pause setting | To stop the daily letter when you ask |
We do not sell personal information. We do not use it for advertising, and we run no analytics tool. Your journal can hold anything you write in it. Do not write a detail there that you do not want us to hold.
Who receives the data
We give personal information only to a company that helps us run Tideglyph. Each one receives the minimum it needs.
| Recipient | What it receives | Where |
|---|---|---|
| Render | Every record. Render runs the app and the database. | Frankfurt, Germany |
| Paystack | Your email address and the amount, to take a payment. The subscription code, to cancel a plan. | South Africa |
| Anthropic | The date and the list of transits for that day, to write the reading text. It receives no email address and no birth details. | Outside South Africa |
| Resend | Your email address and the email text, to deliver the daily letter and the cancel confirmation | Outside South Africa |
| Google Fonts | Your browser asks Google for the page fonts. Google then receives your IP address. | Outside South Africa |
The transfer outside South Africa
Your record sits in Germany, and no copy sits in South Africa. Section 72(1)(a) of POPIA permits the transfer. Each recipient outside South Africa is bound by a data processing agreement, or by a law, that gives your information adequate protection.
How long we keep it
We keep your record until you ask us to delete it. No job deletes a record automatically. We keep a payment record for five years, because section 29 of the Tax Administration Act 28 of 2011 requires it. We tell you when a law stops us from deleting a record.
How we protect it
- Tideglyph answers over HTTPS only.
- A signed cookie keeps you signed in, and it expires after 30 days.
- Paystack takes each card payment on its own page.
- A person with database access can read every record. We keep that access to a minimum.
Your rights
Write to the support address from the email address on your account. We answer within 30 days, and we tell you if we need longer. Tideglyph has no export button and no delete button, so a person answers each request.
| Right | What you may ask |
|---|---|
| A copy, section 23 | To confirm that we hold your record, and to receive a copy of it |
| Correction or deletion, section 24 | To correct a record that is wrong, or to delete your record |
| Objection, section 11(3) | To object to the use of your record |
| No direct marketing, section 69 | To stop a marketing message. We send none. The daily letter is part of the service, and each letter has a pause link. |
| A human decision, section 71 | Not to be subject to a decision that a machine makes alone. We make no such decision about you. |
| A complaint, section 74 | To complain to the Information Regulator |
Cookies
Tideglyph sets one cookie, called tg_session. It keeps you signed in, and it expires after 30 days. Sign out to remove it. We set no analytics cookie and no advertising cookie, so we show no cookie banner.
Children
A child is a person under 18. A child may not hold a Tideglyph account, and we do not knowingly hold a child's information. Write to the support address if you think we hold one, and we will delete it.
A complaint to the Information Regulator
You may complain at any time. You do not need to write to us first.
