Eddies
Privacy Policy
Last updated 1 November 2026
What data Eddies (the montazhka.ai website and the iPhone app) keeps, why, for how long and who else processes it. Data controller: Fiedler Tech LLC (150 E B St, Casper, WY 82601, USA). Questions and requests: support@montazhka.ai.
1. What we keep
| Data | Why | How long |
|---|---|---|
| Uploaded videos, photos, music and editing working files | To edit your video | 1 hour after processing, then deleted automatically. The current version of a Studio project: 72 hours |
| Finished videos in My videos | So you can download them again | 3 days on free access, 30 days with a plan or after paying; you can delete them sooner |
| Studio projects, media library, generated voice-overs and exports, saved styles | Working on the project | Until you delete them or the account |
| Recognised speech text, subtitles, scripts | Subtitles, edits | As long as the video or project they belong to |
| Account: email, password hash, sign-in method, credit balance and spending history, plan | Sign-in, payments, credits | While the account exists |
| IP address when the account is created | Limiting the number of new accounts and preventing abuse | While the account exists |
| The iPhone app: SHA-256 hashes of a random install key and — with the free first video — of the app's identifier for your Apple Account and of the device (identifierForVendor), as signed by Apple; the values themselves are not kept | So the free first video is given once per device | While the service runs; when the account is deleted, the account number is removed from them |
| Technical data about each video: length, file size and format, processing time, the template used, device type (phone / computer, website / app), country from the network — with the internal account number, without the IP address, content or text | Finding errors and making editing faster | 180 days; when the account is deleted, the account number is removed from them |
| What you did in the app and on the site: which steps you took — for example started, saved or shared a video, saw the plans, started or completed a purchase, changed the style. Only the name of the step and one option from a fixed list (for example "saved to Photos"), with the internal account number, device type, language and country from the network — without the IP address, content, text or advertising identifiers | Seeing where people get stuck and improving the service. Not for ads or tracking; not shared with third parties | 180 days; when the account is deleted, the account number is removed from them |
| App Store purchase records (what was bought, amount, date, Apple's transaction id) | Accounting and tax | As long as the law requires, even after the account is deleted |
We never receive or store payment details: purchases are paid through Apple (the App Store). From Apple we receive only signed purchase information — what was bought, dates, the transaction id and a random id of your account for purchases, without your name, email or card details. Speech recognition runs on our own servers.
2. The Eddies iPhone app
The app uses the same account as the website and handles data by the same rules:
- Videos, audio and photos. What you choose or film in the app is uploaded to our server only to edit it, and kept for the periods in the table above. The camera and microphone are used only while you film in the app. From your photo library the app receives only the files you pick, and it asks for Photos access only to save a finished video there.
- An account identifier. A random sign-in key (the
mzcookie) is kept on the device so the server recognises your account. The app doesn't ask for your name, phone number or contacts; an email is only there if you add one. - An install key. The app keeps a random install key in the iPhone's keychain and sends it to our server so the free first video is given once per device; the server keeps only its hash (see the table above).
- Notifications that a video is ready are shown by the device itself; we don't collect push tokens.
- Usage statistics. The app tells our server which steps you took (the opening questions, the editor, saving and sharing a video, plans and purchases, your answer to the notifications request) — with the account number, under the rules and periods in the table above. There's no third-party analytics, and it isn't used for ads or tracking.
- No tracking. The app has no ads, no advertising identifier (IDFA), no third-party analytics and no tracking SDKs. We don't link your data with other companies' data for advertising, and we don't sell it.
3. Who else processes data
To provide the service we share the minimum data needed with these companies (they act on our instructions and, under their API terms, don't train their models on your data):
- Anthropic (Claude) — the text of your speech and your descriptions, to decide what to cut, fix recognition, write the post caption and answer in the Studio chat;
- OpenAI — texts for OpenAI voices, descriptions for stickers and generated clips in the Studio;
- ElevenLabs — when premium voices and sounds are on: the text to voice or the sound description;
- Apple (the App Store) — selling plans and credit packs in the app and taking the payment: you give your payment details to Apple, and we receive only the purchase information from Apple (see above);
- stock footage, music and GIF search (Pexels, Openverse, Wikimedia Commons, KLIPY/GIPHY) receives only search words, never your files;
- the hosting provider whose servers run the service.
Where data is processed outside your country, we rely on standard contractual clauses or another lawful basis.
4. Cookies and browser storage
We use one essential cookie, mz, which keeps you signed in to your account (up to 3 years or until you sign out).
Browser storage remembers your language, currency and editor settings. There are no advertising or analytics cookies.
No cookie is set while you just browse the site — only after your first action. We don't track you across other websites or apps.
5. Legal bases
Performing our contract with you (providing the service, taking payment), legal obligations (payment records), our legitimate interest (preventing abuse, security), and consent where the law requires it separately.
6. Your rights
You can get a copy of your data, correct it, delete it or restrict its processing, object to it, and take it elsewhere. To do so, write to support@montazhka.ai — we answer within 30 days. You can also complain to a data protection authority.
7. Deleting your account and data
You can delete your account yourself: in the app, Settings → "Delete account"; on the website, Account → "Delete my account". Your plan is cancelled, and your finished videos, Studio projects, media library, saved styles, credit balance and history, email, password and sign-in methods are deleted at once; the account number is removed from the technical data about videos. Temporary editing files are deleted within 1 hour. Only the payment records we must keep by law remain. Deletion can't be undone: the account and its credits can't be restored afterwards.
8. Security
Connections are encrypted (HTTPS), passwords are stored only as a hash (scrypt), sign-in links are single-use and expire, and every account sees only its own files.
9. Children
The service is not meant for children under 16, and we don't knowingly collect their data.
10. Changes
We'll announce changes to this policy on the site. The date of the latest version is at the top of the page.
