Privacy policy

Your writing is yours.
GlideProse is a writing tool. It exists to hold your words, organize them, and hand them back to you as a manuscript. This page explains exactly what it keeps, what it never touches, and how to erase all of it.
Last updated October 9, 2026
Who we are
GlideProse is published by NestCalc.ai LLC (Wyoming, USA), which is the controller of the data described here. You can reach us about anything on this page at support@nestcalc.ai.
What we collect
Two things about you, and one about what you've bought.
•
Your account. Your email address and a user id generated when you sign up. Both are required — they are how the app knows the work is yours, and they are used for app functionality and account management. Accounts are email and password, handled by Supabase Auth.
•
Your writing. The answers you speak, the prose GlideProse writes up from them, and any manuscript you import yourself (.docx, .txt or .md). This is stored in your account so it is there on your next device and your next session. Only you can read it.
How your speech is handled
When you talk to GlideProse, your device's own operating system does the transcription — the same speech service your keyboard's dictation key uses. GlideProse never receives, records, transmits or stores audio. Only the text your device produces ever reaches the app.
What your operating system does with that audio while it transcribes is governed by Apple's or Google's privacy policy, not ours. We do not control it and we never see it.
Who processes your writing
To ask you the next question and to write up a chapter, the text of your project is sent to an AI model from Anthropic, through GlideProse's own server function. Two companies touch your writing, both strictly as service providers acting on our instructions:
•
Supabase — hosts the database, the account system and that server function.
•
Anthropic — runs the model that conducts the interview and shapes your write-ups, under standard commercial API terms: your writing is not used to train models.
They are processors, not an audience. Your writing is not sold, and it is not shared with anyone for advertising or any other purpose. Traffic to both is encrypted in transit.
When you subscribe
GlideProse sells auto-renewing subscriptions in two places: in the apps, through the App Store and Google Play, and on glideprose.com. Whoever sells you the plan takes the payment. Your card number, your billing address and every other payment detail stay with them — none of it reaches GlideProse, and there is nothing in the app or on the website that could receive it.
In the apps — the App Store and Google Play. The store takes the payment. Your payment details stay with Apple or Google. To know which plan you are on, GlideProse uses RevenueCat. It is a processor, the same way Supabase and Anthropic are above: it acts on our instructions and it is not an audience.
•
What it receives. The purchase token the store issues, which plan you bought, and an identifier for this installation of the app. It is also given the same user id your account already has, so a subscription follows your account to your next device instead of being stranded on one phone.
•
What it is for. Three things: making the app work, keeping purchases secure and preventing fraud, and managing your account. Nothing else.
On glideprose.com — Stripe and Link. Web subscriptions are sold through Stripe's Managed Payments service, and Link, a Stripe company, is the seller of record. At checkout, Stripe and Link collect your name, email address, billing address and payment method to take the payment, work out and collect any sales tax, VAT or GST, prevent fraud, send your receipts, and help with payment questions. Because Link is the seller, it handles that information under its own privacy policy (link.com/privacy) and Stripe's (stripe.com/privacy), not ours. You can see and manage the subscription through Manage billing on glideprose.com or in your Link account.
From Stripe, GlideProse keeps only what it needs to give you your plan: an id for you as a Stripe customer, the id of your subscription, which plan it is, whether it is active, and when the current period ends. Your invoices and receipts are kept by Stripe, where we can look them up to answer a billing question or issue a refund.
What the account keeps about your plan. For each way you have paid — the App Store or Google Play, glideprose.com, or a plan we have given you — your account keeps one record: the plan, when it ends, and that route's own reference (the store's transaction id, or the Stripe subscription id). Your plan is the best of those records, which is what stops a change on one route from undoing another, and what stops you being charged twice. Every change to these records is also logged: the event's id and type from the store or from Stripe, the plan it asked for, the plan your account ended up on, and when.
What it is used for, and nothing else: giving you the plan you paid for on every device, keeping purchases secure and preventing fraud and double charges, answering billing questions and issuing refunds, and managing your account. It is not used for advertising, analytics, marketing or personalization, and none of it is sold or handed to anyone for their own purposes. A processor is not a third party.
Your plan changes how much the app will do for you. It never changes whose words these are: export is not gated on any plan, at any tier, ever.
When the app crashes
If GlideProse crashes on your phone, a crash report goes to Firebase Crashlytics, a Google service: what the app was doing when it failed, your device model, its operating-system version and its state at that moment (such as free memory and storage), the app version, and a random identifier for this installation of the app. It never contains your writing, your speech, your email or your account id.
Google handles crash reports as a processor, on our instructions, the same way Supabase and Anthropic are above. We use them only to find and fix what broke — never for advertising — and they are kept for 90 days. The website sends none.
What we do not collect
There are no advertisements in GlideProse and no advertising identifier. There is no analytics SDK — the one diagnostic tool is the crash reporter described in When the app crashes.
We do not collect your location, contacts, photos, calendar, messages, browsing history or health information. We never see your card or your payment details — see When you subscribe. The app does not track you across other apps or websites, and there is nothing in it that could.
Deleting everything
You can delete your account from inside the app or on glideprose.com, and it takes effect immediately: your account and every project, chapter, interview answer, write-up and imported draft are erased from our servers. It cannot be undone. Full instructions are on the Delete your account page linked below.
If you have a subscription bought on glideprose.com, deleting your account cancels it at once (see our Terms for what that means for the rest of the period). A subscription bought through the App Store or Google Play is not canceled by deleting your account; cancel it there first.
When your account is deleted, your plan records and the link between your account and Stripe are deleted with it. The log of billing events keeps each event's id and type and the plan it asked for and resulted in, with your account removed from it, so the record of what was charged and granted stays complete for accounting, refunds and disputes. Records of payments themselves are kept by Apple, Google, or Stripe and Link as their own legal and tax obligations require.
Changes to this policy
If what the app collects ever changes, this page changes with it and the date at the top moves. Questions, or a request about your data: support@nestcalc.ai.
