FAQ
Frequently Asked Questions
Everything you need to know about Preserver — privacy, features, platforms and on-device AI.
Pricing & Purchase
How much does Preserver cost?
Preserver is a one-time purchase of $49 USD. That's it — no subscription, no in-app purchases, no add-ons, no renewal fees. Pay once and use it forever.
Is this a perpetual licence?
Yes. Your $49 purchase is a perpetual licence — you own the app indefinitely. There are no renewal fees, no subscription tiers and no features locked behind additional payments. All future updates within the current major version are included.
Are there any hidden costs or premium tiers?
No. There are no in-app purchases, no add-ons and no upsells. Every feature is included in the one-time $49 purchase price. Nothing is hidden behind an additional payment.
Do I need to create an account or register?
No account or registration is required to use Preserver. Your purchase is processed through the App Store or Google Play. Beyond that, we never ask for your name, email or any personal details.
Privacy & Data
Where is my data stored?
On your device, by default. If you choose, you can store your Activities in your personal cloud account (Google Drive, iCloud, Dropbox, etc.). You're always in control — nothing is shared with anyone unless you actively choose to share it.
Do you share my data with third parties?
Never. Preserver does not sell, share, or use your data for AI training. No data is accessible to anyone but you. No ad platform has access to your captures or personal data.
Can I use AI tools on my captured data?
Yes — through your phone's native AI capabilities. Preserver stores your captures privately on your device. You can then use any AI app installed on your phone to review, search or summarise that data. Preserver itself does not include or process AI features. See the AI & Transcription section below for details.
Can Preserver see my captures?
No. Your captures are stored on your device and, if you choose, in your own cloud account. Preserver as a company has no access to what you record. There is no server where your content is uploaded to us.
What happens to my data if I delete the app?
Your data is stored on your device, so deleting the app removes it from that device. If you've backed up to a personal cloud account (Google Drive, iCloud, etc.), your captures remain there under your control.
Features & Capture
What types of media can I capture?
Text notes, voice recordings, photos, and video — all within a single Activity entry. Everything is automatically stamped with date, time and GPS at the moment of capture.
What metadata is captured automatically?
Every capture is automatically stamped with date, time, and GPS coordinates. Unlike most apps, this metadata stays embedded in your data even when you export or share it — so your proof of time and location travels with the record.
Does it work without an internet connection?
Absolutely. Preserver works completely offline — no Wi-Fi, Bluetooth, or mobile data required. GPS capture works via satellite with no network connection at all. Your captures are stored on your device until you choose to back them up or share them.
Does GPS work without mobile signal?
Yes. GPS positioning uses satellites, not mobile towers or Wi-Fi. It works underground, in aircraft, in remote areas, and anywhere else there is no mobile or data signal. This is one of Preserver's most important features for field users.
What is an Activity?
An Activity is a container for a related set of captures — for example, a job site visit, a field research session, or a day's notes. Within each Activity you can mix text, voice, photos and video, all sharing the same timestamp and location context.
How do I export or share my captures?
From within any Activity, you can share directly to other apps, export to your cloud storage, or send via email or messaging. You control exactly what gets shared and with whom. The GPS and timestamp metadata travels with the export.
Can I add notes after the fact?
Yes, you can add additional captures to an Activity at any time. The original captures retain their original timestamps, so the record of when each item was captured is always accurate and tamper-evident.
AI & Transcription
Does Preserver send my audio to any AI service?
No. Preserver never uploads your recordings anywhere. These features use the AI already built into your phone by Apple or Google. You choose when and whether to share a file with it.
Does this work offline?
Recording and exporting in Preserver always work offline. Apple Intelligence transcription and Notes summaries run on-device. Gemini generally requires an internet connection; Pixel Recorder transcription runs on-device.
Is my exported recording still valid as evidence after transcription?
Your original recording in Preserver is untouched — transcription and summarisation work on the exported copy. Keep the original in Preserver (or your export bundle, which includes the timestamped metadata) as your source of record.
What languages are supported?
Transcription language support depends on your phone's speech recognition, not on Preserver. Check your device's language settings — on iPhone under Settings → General → Language & Region, and on Android under your speech/voice input settings.
Which phones support this?
Apple Intelligence requires iPhone 15 Pro or later running a current version of iOS. Gemini is available on most recent Android phones; on-device summarisation features vary by model. Older phones can still transcribe using Notes (iPhone) or share the file to any transcription app of your choice.
Do I need to pay for anything?
No. Apple Intelligence and Gemini's core features are included with your phone. Preserver remains a one-time purchase with no subscription — this workflow adds nothing to that.
My exported video won't open in Gemini — why?
Make sure you're sharing the file directly from Preserver's share sheet, and that you're running the latest version of Preserver. If a file won't open in another app, contact us and we'll help.
Platforms & Compatibility
Is Preserver available on iOS and Android?
Yes — Preserver is available on both the Apple App Store and Google Play Store. Purchase it once and download on either platform.
Is there a desktop or web version?
Currently Preserver is a mobile app for iOS and Android. Your captures can be accessed on desktop by exporting them to your cloud storage (Google Drive, iCloud, Dropbox) and opening them on any device.
What iOS and Android versions are supported?
Preserver supports iOS 15 and above, and Android 8 and above. For the best experience, we recommend keeping your device's OS updated to the latest version.
Can I use Preserver on multiple devices?
Yes. Because there's no account, each device operates independently. If you back up to a shared cloud account (e.g., family Google Drive), captures from multiple devices can be stored together. Direct cross-device sync is on our roadmap.
Professional & Compliance Use
Can I use Preserver for professional or compliance purposes?
Yes. Preserver is used across 40+ industries for timestamped evidence, field records, compliance documentation, and more. The automatic GPS and timestamp metadata makes it suitable for evidence-grade capture in many professional contexts.
Is the timestamp tamper-proof?
The timestamp is captured at the device level at the moment of recording and is not editable within the app. While no digital timestamp is fully tamper-proof in an absolute legal sense, the metadata is embedded and travels with the file, making alterations detectable. For critical legal matters, consult a legal professional.
Can Preserver be used as legal evidence?
Preserver captures are increasingly used to support legal matters — disputes, insurance claims, workplace incidents and more. Whether records are accepted as evidence depends on the jurisdiction and the context. The GPS and timestamp metadata significantly strengthens the credibility of any capture. Consult a legal professional for your specific situation.
